摘要
本文首先针对雷达导引头二相编码步进频(PCSF)的信号形式及处理流程做了简要论述,然后比较了PCSF信号与线性调频步进频(Chirp-SF)信号的优缺点,最后建立了干扰源的信号模型,在压制性干扰和存储转发式干扰环境下,重点分析了PCSF与Chirp-SF信号的细分辨一维距离像的抗干扰效果,并对此作了大量仿真并得出结论。
Signal form and processing flow of two-phase coded step frequency（ PCSF） for radar seeker is depicted briefly; then advantages and disadvantages of PCSF signal LFM step frequency（ chirp-SF） signal are compared;signal model of jamming source is finally set up. In suppression jamming and store and forward jamming condition,antijamming effect of fine resolution 1 dimensional radar profile of PCSF and Chirp-SF signal is analyzed emphatically,and a lot of simulation for this are carried out and conclusion is obtained.
