Barker code,Frank code and P code used in the radar system are presented in the paper.介绍雷达中常用巴克码、弗兰克码、P码等相位编码信号。
A method, which uses Barker code as excited signal, is presented in the paper to overcome the problem.为了提高系统信噪比,本文采用巴克码作为激励信号,利用巴克码所具有的尖锐自相关函数性质来构造匹配滤波器抑制噪声。
Under the condition of zero Doppler frequency shifts,this kind of“waveform pair”is equivalent to polyphase Barker coded waveform at costs of a small amount of loss in signal-to-noise ratio and widening of the bottom of mainlobe.在零多普勒频移条件下，这类“波形对”能以少量信噪比损失为代价使脉压输出波形的主旁瓣比等于码序列的长度，也就是说，从主旁瓣比的角度讲，这类“波形对”可以等效为相应长度的多相巴克码波形。 |
