| 摘 要： | 本文首先讨论了高斯白噪声环境下超宽带（ＵＷＢ）雷达信号设计问题，提出了一种自适应最优波形设计方法。这种方法可以集中目标散射回波能量，从而大大提高了接收信号的信噪比；其次，对杂波干扰下的低能量相干目标环境，根据牛曼—皮尔逊准则提出了一种非线性方程牛顿迭代法，与现有的ＵＷＢ信号方法相比，信噪比要改善１０ｄＢ左右。

| Abstract: | In This paper, methods of the signal design of UWB (Ultra Wideband) radar are probed.Firstly,the problem of signal design of UWB radar under the white noise environment is discussed, and an adaptive optimimum waveform design method is presented.This method can collect 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 given out. Compared with the other methods which were discussed in home and abroad, its SNR improves about 10dB |
