浮空雷达高精度探测分析

Analysis of high precision detection for aerostat-borne radar

浮空雷达探测精度主要受平台姿态变化引起的定位误差和传感器自身的探测误差影响。文章针对2类误差的影响因素进行了分析,提出了采用宽信号发射波形和高精度定位的方法来降低雷达探测误差,结合高精度船舶自动识别系统(automatic identification system,AIS)信息自动校准进行误差补偿,实现浮空雷达高精度探测。工程实测数据分析表明,该方法取得了较好的效果。

The detection performance of the aerostat-borne radar suffers from the aerostat platform positioning biases and sensor＇s detecting biases. The effect of these two kinds of biases is analyzed and the high precision detection method is presented. The technique adopts the transmit waveform of the wideband signals and employs the high precision location to reduce the error of radar detection, where the automatic identification system（AIS） automatic calibration is used for error compensation. The results of processing engineering application measurement data show that this method is effective.
