通过建立尺度空间新内积、新范数的方法来构造新型小波变换 ,并且实现了用该系列小波变换对雷达弱信号去噪的目的 .研究结果发现该种小波可以设计成具有“正交”性质和可调参数的对称小波变换 .采用对一个真实的雷达信号建立仿真信号方法说明该方法能够有效地检测出弱雷达信号
This paper constructs a new wavelet transform by establishing a new inner product and new norm of scale space and realizes the purpose of de-noising the weak signal of radar by using this series of wavelet transform.It is found that this kind of wavelet can be designed to have “orthogonal” Symmetric wavelet transform with properties and tunable parameters.Using the method of simulating a real radar signal shows that this method can effectively detect weak radar signals
