Firstly,this paper analyzes the principle of linear FM pulse jamming to SAR through SAR imaging processing.Secondly,the properties and detection method of linear FM pulse jamming are analyzed.Then we lay heavy stress on the methods of suppressing the slope-depressed linear FM pulse jamming through notch filter and parametric method,that is,the linear FM pulse jamming is suppressed by filtering in fractional Fourier domains.Finally,the simulations are executed,and the results are given and analyzed.
