| 摘 要： | 提出了一种单脉冲机载火控相控阵雷达的主杂波谱区低速运动目标检测方法,该方法结合单脉冲精确测角和杂波谱展宽后在频域能量分散的特点,采用多普勒通道测量角度值与其对应的杂波单元的角度值的误差作为检测统计量,以实现极低速地面运动目标的检测.分析和仿真结果表明,在波束扫描方位角增加引起杂波谱严重展宽时,该方法仍然具有良好的极低速运动目标检测性能.

| Abstract: | A ground moving target detection approach in main-lobe clutter spectrum region is proposed for monopulse airborne fire-control phased array radar. The approach takes advantage of both monopulse azimuth measurement and spread of clutter energy in frequency domain, and a statistical detector of azimuth error in each Doppler channel is obtained. The simulation results for low-speed ground moving target detection show that the approach has still a good detection for very-low-speed moving targets even if the azimuth increase results in serious spread of main-lobe clutter spectrum. |
