Window Function Acousto-optic Correlator and Its Appplication in Radar Signal Processing

摘要: 介绍了一种只使用一个声光器件的窗口函数声光相关器,它可实现滤波片的窗口函数与电信号的震幅调制函数之间的相关运算,对由单载频矩形脉冲雷达信号与无调制随机杂波干扰组成的模拟回波信号进行了抗干扰实验,实验结果表明,当雷达信号脉宽为2 μs时,相关增益达到15 dB。

Abstract: In this paper a window function acousto-optic correlator which includes one AOD is given. It can complete the correlation between the window function of a filter and the amplitude modulation function of a electric signal. We have done a interference-free experiment for a imitative back wave singal, which is composed of a rect pulsed radar signal with signal carrier-frequency and a radom interference signal without modulation. When the pulse width of the radar signal is 2 μs, the correlation gain is 15 dB.
