Study of range-extended target detection performance based optimized EBSPK signals.

Extended-binary phase shift keying (EBSPK)-MODEM radar-communication transceiver is considered as high-range resolution (HRR) radar in the ranging mode. In this paper, a new range-extended target detection method for EBPSK transceiver is investigated. First, the signal to noise ratio (SNR) improved amount of the proposed system is deduced. Secondly, Mean square error (MSE) of target scattering parameter is estimated. The optimal EBPSK waveform is designed to make sure that the estimated performance of the target frequency domain scattering parameters is optimal. Target detection performances of the optimized EBPSK signal in the additive white Gaussian noise (AWGN) channel and the dispersive channel are investigated, respectively. Finally, through optimizing carrier frequency and modulation parameters, the simulation experiment results showed that detection performance of the optimized EBSPK signal is better than the unoptimized EBSPK signal and traditional radar signals.
