摘要
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。
Because the main lobe of coastal phase-array radar is touching the offing, the sea clutter＆#39;s amplitude is exceeding the signal;leading to the measuring radar being difficult to continuously track the high-speeding and small multi-target over the sea. Consequently, some measures are proposed to reduce in full measure the effects of sea-clusters on radar tracking, which include optimizing radar waveform, improving signal processing mode and using intermediate frequency target simulator and video record replay system to research sea clutter＆#39;s characteristics. The practice shows that these measures can effectively improve the capability of the radar to track multi-targets.
