Design of an optimal radar signal waveform for a range-doppler spreading channel

Abstract

This paper deals with the optimal radar waveform design problem using the quadratically constraint quadratic programing (QCQP) in the narrowband signal echo to range-doppler extended target regime. The solution is obtained in the sense of signal to interference plus noise ratio(SINR) maximization with resolution and fixed transmit power constraints. The performance is compared with other conventional waveforms such as continuous wave (CW) pulse and linearly frequency modulated (LFM) pulse, in terms of resolution through ambiguity function.
