战场侦察雷达与光学传感器指示交接技术算法研究

Research of cueing and handoff technology for battlefield surveillance radar and IRST

摘要:

针对二坐标警戒雷达对三坐标光学传感器传感器目标指示交接问题进行研究，由于二坐标雷达缺少对目标俯仰角的测量信息，难以向三坐标光学传感器传感器提供准确的指示信息，在交接中无法进行准确的坐标变换的处理，导致雷达对光学传感器指示交接效率低下。首先，利用目标信息的先验知识建立了二坐标指示信息的概率描述模型;随后对不同坐标系之间的转换进行描述，并用蒙特卡罗采样法解决不同传感器之间坐标转换问题;最后，针对机械伺服的光学传感器设计了搜索算法，优化了光学传感器搜索空域大小和视域编排顺序，解决机械伺服传感器在对目标的指示交接中存在的搜索视域编排不合理、耗时较长等问题。仿真实验验证了该方法的有效性。

Abstract:

According to the research of the two coordinate warning radar, the three coordinate optical sensor sensor target indication connection problem is studied. Because the two coordinate radar is lack of the measurement information of the target pitch angle, it is difficult to provide accurate indication information to the three coordinate optical sensor sensor, and the accurate coordinate transformation can not be processed in the connection. The sensor is inefficient in indicating the handover of sensors. First, the probability description model of two coordinate radar indication information is established by using the prior knowledge of the target information. Then the Monte Carlo sampling method is used to solve the transformation of the indication information from the two-dimensional coordinate system to the three-dimensional coordinate system. Finally, the search algorithm is designed for the mechanical servo optical sensor, and the optical sensor search is optimized. The problem of unreasonable wavefront arrangement and long time-consuming in the process of indicating and handing over targets by mechanical servo sensors is solved by arranging the space size and wavefront sequence. The effectiveness of the method is verified by the simulation experiment.
