Abstract :
The problem of designing radar detection filters that minimise sidelobe levels in both Doppler and range co-ordinates is considered. The new algorithm for a Doppler optimised mismatch filter is constructed. The generalisation enables sidelobe suppression for the polyphase and complex multilevel sequences. For minimax filter coefficients calculation, the iterative reweighted least-square procedure is successfully applied. Favourable experimental results are obtained, especially for polyphase codes.
