技术领域Technical Field
本发明涉及空间科学、微波遥感技术领域，更具体地，涉及一种微波综合孔径遥感系统。The present invention relates to the fields of space science and microwave remote sensing technology, and more specifically, to a microwave synthetic aperture remote sensing system.
背景技术Background technique
星载遥感系统是指搭载在卫星上通过接收地物反射的电磁波对地物进行观测的系统。目前，国内外对地遥感系统根据电磁波频段可以分为光学遥感和微波遥感，根据轨道高度可以分为中低轨卫星和高轨卫星。A satellite-borne remote sensing system refers to a system that is carried on a satellite and observes ground objects by receiving electromagnetic waves reflected by the ground objects. At present, domestic and foreign ground remote sensing systems can be divided into optical remote sensing and microwave remote sensing according to the frequency band of electromagnetic waves, and can be divided into medium- and low-orbit satellites and high-orbit satellites according to the orbital altitude.
现有光学遥感卫星有着分辨率高，成像简单易于实现的优点，但容易受天气和光照条件限制，因此无法全天时，全天候对地观测，受限较大。相较之下，微波遥感系统不受光照条件限制，能够透过云层实现全天候全天时对地观测。然而相比光学遥感系统，微波信号频率低，波长长，从而实孔径天线分辨率低至10公里量级，无法满足对地观测需求。因此，目前国内外通常采用合成孔径雷达（SAR）成像技术进行对地观测，SAR利用卫星与观测目标的相对运动把尺寸较小的真实天线孔径用数据处理的方法合成一较大的等效天线孔径的遥感系统，从而实现高分辨率对地观测。Existing optical remote sensing satellites have the advantages of high resolution and simple and easy imaging, but they are easily restricted by weather and lighting conditions. Therefore, they cannot observe the earth all day and all weather, which is very limited. In contrast, microwave remote sensing systems are not restricted by lighting conditions and can achieve all-weather and all-day earth observation through clouds. However, compared with optical remote sensing systems, microwave signals have low frequency and long wavelength, so the real aperture antenna resolution is as low as 10 kilometers, which cannot meet the needs of earth observation. Therefore, synthetic aperture radar (SAR) imaging technology is generally used for earth observation at home and abroad. SAR uses the relative motion between the satellite and the observation target to synthesize the smaller real antenna aperture into a larger equivalent antenna aperture remote sensing system through data processing methods, thereby achieving high-resolution earth observation.
国内外现有的微波遥感卫星系统主要基于低轨卫星实现，而在轨的高轨微波遥感卫则通过SAR对地观测。但是SAR成像技术需要卫星对地相对运动，这会造成重返周期问题，无法长期对目标区域进行观测。The existing microwave remote sensing satellite systems at home and abroad are mainly based on low-orbit satellites, while the high-orbit microwave remote sensing satellites in orbit observe the earth through SAR. However, SAR imaging technology requires the satellite to move relative to the earth, which will cause the re-entry cycle problem and make it impossible to observe the target area for a long time.

The first high-orbit microwave remote sensing satellite is stationary relative to the ground. The echo signal reflected from the ground is received through the ultra-large comprehensive aperture formed by multiple satellites, and the echo signal is processed, thereby realizing long-term high-resolution observation of the ground area of interest.

相比单颗卫星接收天线孔径（D<20m）对应的分辨率（>18km），所述遥感系统分辨率提升500倍以上，所述遥感系统与现有高轨合成孔径雷达分辨率（20m）相当，并且不存在重返周期问题，可以全天时全天候对地某区域进行长期高分辨率观测。Compared with the resolution (>18km) corresponding to the aperture of a single satellite receiving antenna (D<20m), the resolution of the remote sensing system is increased by more than 500 times. The remote sensing system is equivalent to the resolution of existing high-orbit synthetic aperture radars (20m), and there is no re-entry cycle problem. It can conduct long-term high-resolution observations of a certain area on the ground around the clock and in all weather conditions.

对至少两颗第一高轨微波遥感卫星进行编队，形成高轨卫星编队；其中，所述第一高轨微波遥感卫星用于接收回波信号，并工作于同一地球同步轨道；Forming a formation of at least two first high-orbit microwave remote sensing satellites to form a high-orbit satellite formation; wherein the first high-orbit microwave remote sensing satellites are used to receive echo signals and operate in the same geosynchronous orbit;
获取所述高轨卫星编队的星间距离以及时频信息；Obtaining the inter-satellite distance and time-frequency information of the high-orbit satellite formation;
令所述第一高轨微波遥感卫星响应于针对目标区域观测微波信号事件的关联触发信号，接收对应的回波信号；Instructing the first high-orbit microwave remote sensing satellite to receive a corresponding echo signal in response to an associated trigger signal for observing a microwave signal event in a target area;
根据所述星间距离、所述时频信息及所述回波信号，确认综合孔径的观测结果。The observation result of the synthetic aperture is confirmed according to the inter-satellite distance, the time-frequency information and the echo signal.

上述优选实施例中，多颗第一高轨微波遥感卫星接收到来自于地面的回波信号后将多颗卫星的回波信号进行相干处理，从而等效为由多颗卫星接收天线构成的超大天线，即综合孔径进行对地观测。In the above preferred embodiment, after receiving the echo signals from the ground, multiple first high-orbit microwave remote sensing satellites perform coherent processing on the echo signals of multiple satellites, thereby being equivalent to an ultra-large antenna composed of multiple satellite receiving antennas, that is, a comprehensive aperture for earth observation.
在一些可选实施例中，在接收到所述高轨卫星编队中各个所述第一高轨微波遥感卫星的所述时频信息后，若各个所述时频信息为非同步状态，则对各个所述第一高轨微波遥感卫星间的时频差值进行估计，并在对所述回波信号进行处理时，根据所述时频差值进行补偿，使得所述第一高轨微波遥感卫星接收到的所述回波信号可进行相干处理，从而实现信号增益，得到综合孔径的观测结果。In some optional embodiments, after receiving the time and frequency information of each of the first high-orbit microwave remote sensing satellites in the high-orbit satellite formation, if each of the time and frequency information is in an asynchronous state, the time and frequency difference between each of the first high-orbit microwave remote sensing satellites is estimated, and when processing the echo signal, compensation is performed according to the time and frequency difference, so that the echo signal received by the first high-orbit microwave remote sensing satellite can be coherently processed, thereby achieving signal gain and obtaining the observation result of the comprehensive aperture.
在另一些可选实施例中，在接收到所述高轨卫星编队中各个所述第一高轨微波遥感卫星的所述时频信息后，若各个所述时频信息为同步（对齐）状态，则可视为不需要根据时频信息对所述回波信号进行补偿，此时在考虑星间距离补偿的基础上，使得多颗卫星接收到的所述回波信号可进行相干处理，从而实现信号增益，得到综合孔径的观测结果。In other optional embodiments, after receiving the time-frequency information of each of the first high-orbit microwave remote sensing satellites in the high-orbit satellite formation, if each of the time-frequency information is in a synchronized (aligned) state, it can be considered that there is no need to compensate the echo signal based on the time-frequency information. At this time, on the basis of considering the inter-satellite distance compensation, the echo signals received by multiple satellites can be coherently processed, thereby achieving signal gain and obtaining the observation results of the comprehensive aperture.
本领域技术人员应当理解，通过令所述高轨卫星编队进行时频同步，可使得接收到的各个所述第一高轨微波遥感卫星的所述时频信息呈同步状态。Those skilled in the art should understand that by making the high-orbit satellite formation perform time and frequency synchronization, the time and frequency information received from each of the first high-orbit microwave remote sensing satellites can be synchronized.

Therefore, it is necessary to achieve high-precision ranging between the first high-orbit microwave remote sensing satellite in the high-orbit satellite formation and obtain high-precision time and frequency information (i.e., the time-frequency information) of multiple satellites.
在一些优选实施例中，所述方法还包括：In some preferred embodiments, the method further comprises:
调节所述第一高轨微波遥感卫星间的星间距离，以得到指定分辨率的所述观测结果。The inter-satellite distance between the first high-orbit microwave remote sensing satellites is adjusted to obtain the observation result with a specified resolution.
需要说明的是，由于孔径越大，分辨率越高，通过调节所述星间距离可实现综合孔径的调节，进而实现更高分辨率。It should be noted that since the larger the aperture, the higher the resolution, the comprehensive aperture can be adjusted by adjusting the inter-satellite distance, thereby achieving a higher resolution.
在一些优选实施例中，所述方法还包括：在令所述第一高轨微波遥感卫星接收所述回波信号前，调节所述第一高轨微波遥感卫星的姿态。In some preferred embodiments, the method further includes: adjusting the attitude of the first high-orbit microwave remote sensing satellite before allowing the first high-orbit microwave remote sensing satellite to receive the echo signal.
