超低空掠海目标的微波探测系统设计

以低空突防技术研究为背景,从脉冲多普勒原理出发设计了微波探测系统,其主要目的实现对海面超低空来袭目标的有效探测。在实验室阶段实现了对移动目标的探测,针对微波探测进行了信号采集系统的电路设计与分析,并采用低通滤波和直流耦合的方式,得到目标信号。在探测实验中对脉冲产生电路,滤波电路及比较电路进行设计和分析验证。实验证明,该信号处理电路性能优良,工作可靠,对目标实现了有效探测。最后,根据实战情况对脉冲电路和滤波电路做了改进,能基本上满足超低空掠海目标的微波探测技术要求。

Low altitude sea-skimming target detection system design of microwave

To low altitude penetration technology research as the background,it design detection system of microwave.If the system can make effective detection for incoming targets at low altitude surface,it realize the main purpose.Through doing many experiments,the system achieved the right detection for moving target in the laboratory stage.It carries out signal acquisition system circuit design and analysis for detection of microwave.To get target signal the detection system uses low-pass filter and dc coupling.In...
