多通道复杂海杂波模拟器设计

对海作战装备雷达系统在目标探测过程中接收到的回波信号既包含目标回波信号,也包含来自海面的反射信号,即海杂波信号。海杂波信号的存在严重限制了雷达系统对目标探测和识别能力,为正确评价雷达系统的相关性能,为雷达信号处理方案的选择提供理论依据,对海杂波信号的精确模拟与仿真已成为雷达信号处理领域中的重要课题,对提高对海作战雷达系统的性能具有重要意义。在此基础上,首先总结了海杂波信号产生的理论基础及相关模型,提出了一种多通道复杂海杂波模拟器设计思路及设计方案,最后给出了测试验证结果。

Design of Multi-channel Complex Sea Clutter Simulator

The echo signals received by radar system of the sea combat equipment during target detection include both the target echo signals and the reflected signals from the sea surface,that is sea clutter signals.The existence of sea clutter severely limits the radar system’s abilities of detecting and recognizing target.In order to correctly evaluate the relative performance of radar system and provide a theoretical basis for the selection of radar signal processing schemes,the accurate simulation of sea clutter signal has become important topic in the field of radar signals processing,also it is of great significance to improve the performance of sea combat radar system.Based on the above backgrounds,this paper firstly summarizes the theoretical basis and related models of sea clutter signal generation,then proposes a design idea and scheme for multi-channel complex sea clutter simulator,finally gives the test verification results.
