Digital Realization of Multiple Artificial Target Jamming on Velocity

A deceptive jamming method based on digital radio frequency memory(DRFM) is proposed. Multiple artificial targets jamming in velocity is realized. Modulation of jamming information is described in detail. Regarding the problem of too much resource needed when modulating multiple artificial targets in velocity, method of data holding is used, and the condition of using the method is analyzed. The problem of high peak to average power ratio when generating multiple artificial targets in velocity at the same range cell, phase shifting is made use of to reduce the peak to average power ratio thereby achieving better effects.
