The issue of range sidelobe suppression filters for biphase coded signals is investigated. By analysing the characteristic in frequency domam, a design method for minimized peak sidelobe filters, which is suited for various code length is suggested. The computer simulation of sidelobe suppression is made based on 190-bit biphase coded signals. This paper presents a method to improve the Doppler-tolerance by combining the frequency diversity and non-coherent sidelobe reduction filters. The simulation results show that the peak sidelobe reduction filters meet the requirements
of modern radar systems.
