High PRF and high duty-cycle quasi-continuous wave system is studied in this paper. Cascade integrator comb filter instead of FIR filter is used as anti-aliasing digital narrowband filter. This paper analyzes the amplitude-frequency characteristic of cascade integrator comb filter and points out its shortcomings and improved methods. And this paper realizes the simulation of quasi-continuous wave system. Finally SNR loss of quasi-continuous wave system is calculated.
