背景技术Background technique
针对射频探测系统主波束内多目标探测与分辨的问题，传统获取主波束内多目标的数据均采用实验室内场或若干外场试验的形式进行。但是，这种形式一方面无法保障数据的连续性；另一方面获取的数据与对应数据的基本属性(如目标之间的相对位置信息、目标之间的相对运动状态等)之间无法实现有效映射，造成算法设计与方法研制没有大量有效的数据进行验证与支撑。In view of the problem of multi-target detection and discrimination in the main beam of the RF detection system, the traditional acquisition of multi-target data in the main beam is carried out in the form of laboratory in-field or several out-field tests. However, on the one hand, this form cannot guarantee the continuity of the data; on the other hand, the acquired data and the basic attributes of the corresponding data (such as the relative position information between the targets, the relative motion state between the targets, etc.) cannot be effectively Mapping, resulting in algorithm design and method development without a large amount of effective data to verify and support.
另外，传统射频探测系统的性能测试与数据获取两者不可同时进行，对数据采集与属性获取的方式大部分采用手动标注的形式，该方法会造成数据获取的成本高、代价大、人力资源投入较多，无法实现数据与属性之间的自动化配准与一体化设计，采集与属性标注系统的可扩展性较差，大幅增加研制周期，降低数据处理效率。In addition, the performance test and data acquisition of the traditional RF detection system cannot be performed at the same time. Most of the methods of data acquisition and attribute acquisition are in the form of manual annotation. This method will result in high data acquisition cost, high cost, and human resource investment. It is impossible to realize automatic registration and integrated design between data and attributes, and the scalability of the acquisition and attribute labeling system is poor, which greatly increases the development cycle and reduces the efficiency of data processing.
