Abstract :
Complementary phase-coded signals have found widespread use in radar systems utilizing pulse compression technique due to their unique autocorrelation properties. However, nonzero sidelobe values appear when the complementary signals pass through the system with limited bandwidth. This paper gives a detailed discussion on the impact of passband cutoff frequency, passband ripple, transition bandwidth, and minimum stopband attenuation of FIR digital filter on sidelobe elevation. At last this paper gets some useful conclusions which are conducive to system design optimization and sidelobe suppression research.
