摘　　要：P波段信号广泛应用于遥测通信中,而P波段充满了广播、通信和雷达信号。用于遥测侦察的宽带侦察接收机需要适应复杂的电磁环境。介绍了一种中心频率450MHz、相对带宽110%的宽带侦察接收机,针对复杂电磁环境,提出了梳齿滤波的方案,兼顾成本和可靠性,一定程度上解决了宽带侦察接收机适应复杂电磁环境的问题。该宽带侦察接收机完成了指标测试及外场试验,工作性能良好。P-band signals are widely used in telemetry communication.There are full of broadcast signals,communication signals and radar signals in P-band.The wide band reconnaissance receiver for telemetry and reconnaissance need to adapt to the complicated electromagnetic environment.This paper introduces a wide band reconnaissance receiver with center frequency 450 MHz,relative bandwidth up to 110%,aiming at the complicated electromagnetic environment,presents a comb filtering scheme,which give consideration to both cost and reliability,the problem of wide band reconnaissance receiver adapting to complex electromagnetic environment is solved to some extent.The wide band reconnaissance receiver has completed the index test and field experiment,and the working performance is good.
