Abstract

The deceptive jamming method is one of the effective ways to jam SAR, and in order to implement deceptive jamming, not only should we estimate the main parameters such as frequency, pulse width, PRF, etc, but also need to locate the jammed SAR. This paper is mainly talking about the effect of SAR platform position error on the deceptive jamming. The accuracy of the jammed SAR position required for deception jamming is deduced according to the given precision of deceptive target position. The bistatic location method is adopted in this paper to locate SAR platform and the accuracy of this location method is also analyzed. Besides, an improved new jamming method which calls for azimuth and elevation angle measurement only is introduced and its angular error effect on deceptive jamming is discussed. The location difficulty can be reduced with this improved jamming method which makes it more feasible to put into practice.

Keywords: Bistatic location, deceptive jamming, position error effect, SAR, electronic countermeasure (ECM), azimuth, elevation angle, Doppler frequency, AOA, bistatic location method
