摘 要:
多通道接收系统在通信、雷达等方面得到了非常广泛的应用，而每个通道自身通频带内频率特性的起伏变化及各个通道之间频率特性的不一致性会对信号的传输造成一定的影响。针对多通道接收系统的上述问题人们提出了线性调频信号补偿法来补偿信号的失真，这种方法可以达到补偿的目的，但补偿效果不是很好。为了提高补偿的精度，在本文中提出了扫频信号补偿法。经过仿真计算，验证了这种方法的有效性，并对它的补偿效果和用线性调频信号补偿法的效果进行了对比分析。[著者文摘]

Abstract:
Multi-channel receiver systems have been widely used in communications, radar and other aspects, and the signals will have been affected by the self-channel frequency band changes and the ineonsistencies of frequency characteristics in the transmission. Usually, people use linear FM compensation to compensate the multi-channel receiver system on the above issues take about. This method can achieve the purpose of compensation, but the compensation effect is not very good. In order to improve the accuracy of compensation, this paper raises another method： sweep signal compensation. After simulation, tests the effectiveness of the method, compares and analyses its result with the linear FM compensation.[著者文摘]
