Bistatic Sar Jamming

Bistatic synthetic aperture radar (Bi-SAR), as currently a major military reconnaissance weapon, plays an increasingly prominent role in modern electronic wars. Therefore, the research on Bi-SAR jamming has become an important issue in the field of electronic warfare.At present, there are a large number of maturely research results on single SAR jamming , however, due to the characterizes of Bi-SAR, which include the transmitter and receiver located in separate plants, and own strong anti-interference capability. When come to interference this system, few effective jamming method has been used, and they are short of theoretical innovation. In this paper, based on the properties of Bi-SAR, the research work is achieved as follows:1.The research on the power property of Barrage-type jamming to Bi-SARBased on the interference equation of Bi-SAR, the product of parameters such as transmitting power, which are related to the transmitter was equated to the echo intensity detected by the jammer, and the interference equation(J/S) was simplified. We deduced the coverage area of J/S contours under the condition that J/S reached a feasible value.. Then the characteristic of the area and its relationship with jammer parameters were analyzed.2. The analysis on the property of Deceptive jamming to Bi-SARBi-SAR system is characterized by strong anti-interference capability, this paper analyzes the deceptive jamming to the Bi-SAR with non-precision positioning receiver. The model of deceptive jamming against Bi-SAR is given, then the defocus issue of deceptive jamming is studied. Through theoretical analysis, it can ascertain the scope of the permission settings and generate the deceptive jamming signals under the condition of tolerable focus.The research on anti-jamming methods based on the signal difference3. The research on anti-rebound jamming method based on ICABased on the mathematical properties of echo and jamming signals, we have analyzed the model difference between the targets echo and jamming signals as the example of rebound jamming. Thereby, in the anti-interference environment which based on the statistical characteristics of signals, we propose the effective interference methods to Bistatic SAR.
