摘要
从频域分析了脉冲多普勒(PD)雷达的信号特点,研究了PD雷达滤波器组带宽设置与雷达重频关系,结合噪声调频干扰对相位检波接收机的影响,给出了干扰PD雷达的合理带宽。最后结合雷达对抗装备的侦察和引导间的关系分析了实际运用中的干扰带宽的设置。
This paper analyzes the signal characteristics of pulse Doppler(PD) radar in frequency domain,studies the relation between the bandwidth setting of filter unit in PD radar and the pulse repetition frequency(PRF) of radar,combining with the influence of the noise frequency modulation jamming on the phase detection receiver,gives the reasonable bandwidth jmming PD radar,finally analyzes the jamming bandwidth setting in practical application combining with the relation between the reconnaissance and guidance in radar countermeasure equipment.
