Abstract
The well known Lewis-Kretschmer P4 polyphase pulse compression codes are low sidelobe, Doppler tolerant codes based on sampled linear FM phases. This paper discusses and shows how the sidelobes can be substantially reduced by applying different weighting techniques and their tradeoffs. Also, a comparison is made with nonlinear chirp P(n,k) polyphase codes
