Outline
Bistatic radar is widely used in military field by virtue of its good anti-jamming ability and accurate detection and identification ability, and how to effectively jam this transceiver-split radar system has become a current research hotspot. Typical jammers have large fluctuations of bistatic RCS with angle change and weak bistatic scattering strength, which are not advantageous in countering bistatic radar. Therefore, a new type of combined jammer against bistatic radar is proposed by analyzing the bistatic scattering characteristics of four types of typical jammers. Afterwards, electromagnetic simulation calculations are carried out on the new combined jammer monomer/array of different bands, sizes and spacings to study the bistatic scattering characteristics under different parameters, and compared with typical jammers. The results show that the new combined jammer monomer/array has strong bistatic scattering strength and the fluctuation amplitude of its RCS with respect to angle is smaller, with good bistatic scattering characteristics, providing technical support for effectively jamming of bistatic radar.
