| 摘 要： | 对于环境复杂的海面,雷达回波中包含了目标回波、海杂波、气象杂波以及干扰信号等.由于海杂波特性随时间变化存在较大的随机性,因此预警雷达在强杂波环境下探测微弱目标时,海杂波抑制成为一个关键环节.恒虚警率(CFAR)处理技术是减小海杂波影响的一项有效措施.本文从海面雷达回波特性入手,分析了海杂波的空间幅度特性,提出一种改进的...

| Abstract: | Radar echo of sea complex environments contains the echo of target,sea clutter,weather clutter and jamming signals.The sea clutter characteristics changed with time has more randomness,the sea clutter suppression becomes a key step,while the early warning radar detects the dim target in strong clutter environments.Constant-false-alarm rate(CFAR) processing is an effective method to suppress sea clutter.In this paper,the characteristics of spatial magnitude of sea clutter is analyzed from radar echo characte... |
