Abstract
Vulse radar signal is widely used in radar countermeasure and detection. When pulse radar signal is adopted in radio frequency simulation (RFS) for radar countermeasure, the target echo will return before the pulse signal is totally transmitted because the size of anechoic chamber is small. The reflected signal and transmitted signal will be coupling and the radar countermeasure cannot be implemented. In this paper, the interrupted transmitting and receiving (ITR) method is adopted to solve the coupling between transmitted and reflected signal. The equivalent simulation method for radar countermeasure and detection is proposed. Then, the processing and detection results of ITR echo and complete pulse radar echo with typical convolution noise jamming are both compared and analyzed. Simulations are conducted to indicate that the detection results of ITR echo are identical with those obtained by the complete pulse echo in the same jammer to signal ratio (JSR). Therefore, the proposed simulation method is effective and applicable.
