Abstract：In the Adaptive Side Lobe Cancellation(ASLC) system of general radar, the mismatched phase of transmission line between the antenna and the former of the receiver can not be ignored usually. Otherwise, the existing method of adaptive channel equalization can only equalize the mismatched amplitude and phase of the receiver while it is disabled of the mismatched phase of the transmission line, because the reference signal is inputted in front of the receiver. Therefore the performance of ASLC is affected. Two methods of modified adaptive channel equalization are provided in this article. The mismatched amplitude and phase of the receiver and the transmission line can be revised at the same time by these two methods. The effect of them is proved with the theory analysis and experimental results.
