Abstract :
In this paper, methods of the signal design of UWB (Ultra-Wideband) radar are probed. A adaptive optimum waveform design method is presented, this method can collected the energy of target scattering return, and improve the signal-to-noise ratio of receiving signal. Then, a Newton iterate method of nonlinear equation based on Neyman-Pearson Criterion, under the LEC conditions, is presented. Compared with the other methods which were discussed in domestic and abroad, it´s SNR is about improved 10 dB
