The invention discloses a 
radar suppressing jamming and deception jamming identification method based on a 
signal cone. The 
radar suppressing jamming and deception jamming identification method mainly aims to solve the problems that jamming characteristics extracted in the prior art are not steady, and the 
identification rate of jamming types is low under the condition of a low or high jamming to 
noise ratio. The 
radar suppressing jamming and deception jamming identification method comprises the steps that 1, target or jammed 
baseband signals are obtained; 2, jamming 
signal error angles mu between jamming signals and a real target 
echo signal are calculated; 3, a threshold angle theta is set as 80 degrees, the 
signal cone is obtained by using theta as a cone angle and using the real target 
echo signal as a center axis, the jamming signals located outside the cone are defined as suppressing jamming, and the jamming signals located inside the cone are defined as deception jamming; 4 the jamming signal error angles mu are compared with the threshold angle theta, and the types of jamming are determined. Jamming characteristics extracted in the radar suppressing jamming and deception jamming identification method are steady, the types of the suppressing jamming and the deception jamming are effectively identified by using the conception of the signal cone under the condition of the high or low jamming to 
noise ratio, and the radar suppressing jamming and deception jamming identification method can be used for anti-jamming, target detection and target tracking of radar.
