用于完成海面低空快速多目标跟踪测量的海岸基相控阵雷达由于主瓣掠地或掠海,导致接收的主瓣杂波过强,主瓣杂波折叠到目标跟踪单元,导致在某些角度对消后的杂波比回波信号还强,以致无法保证连续跟踪测量目标。提出通过优化雷达信号波形、改善信号处理方式、利用中频目标模拟器和视频记录回放系统研究杂波特点等方法措施,最大限度地降低海杂波对雷达跟踪的影响,实践证明能有效提高雷达跟踪海上多目标的能力。
Coastal phased array radars used to perform low-altitude, fast, multi-target tracking surveys of the surface of the sea cause predominantly loiter clutter in the main lobe due to swept or swept main lobe and cause the mainlobe clutter to collapse to target tracking units, The angle of the clutter after the cancellation of the echo signal is also stronger, resulting in continuous tracking can not guarantee the measurement of the target. This paper proposes to reduce the influence of sea clutter on radar tracking by optimizing the waveform of radar signal, improving the signal processing method, using IF target simulator and video recording and playback system to study the characteristics of clutter, and it is proved that radar tracking can be effectively improved Multi-target capability at sea.
