针对外辐射源雷达等采用双基地配置的雷达在探测加速运动目标时,现有的模糊函数无法用于分析目标的距离、速度和加速度参数受双基地雷达几何配置影响的不足,提出了一种能够表示双基地几何配置的双基地雷达距离-速度-加速度模糊函数,并以此为工具分析了双基地雷达目标参数估计性能与双基地雷达几何配置的关系,研究了在不同的双基地几何配置下目标速度和加速度分辨性能、积累增益损失以及最优积累时间等相关问题,并分别给出了其随着双基地雷达基线距离、目标接收方位角和目标与接收站之间距离的变化趋势.为分析外辐射源雷达等双基地雷达对加速目标的探测性能提供了一定的理论参考.
In the case of detecting radars with bistatic targets and using radar with bistatic configurations, the existing ambiguities can not be used to analyze the target distance and the parameters of velocity and acceleration are affected by the bistatic radar geometry configuration. The bistatic radar distance-velocity-acceleration fuzzy function can be expressed as a bistatic geometry configuration. Based on this tool, the relationship between the bistatic radar target parameter estimation performance and the bistatic radar geometry configuration is analyzed. In different bistatic geometry configurations Lower target speed and acceleration resolution performance, accumulated gain loss and optimal accumulation time, and give the trend of them along with the bistatic radar baseline distance, the target receiving azimuth and the distance between the target and the receiving station respectively. It provides a theoretical reference for analyzing the detection performance of accelerating targets such as bistatic radar.
