Equivalent simulation method for motion characteristic of electromagnetic radiation source

Abstract

The invention discloses an equivalent simulation method for a motion characteristic of an electromagnetic radiation source. The method comprises the following steps: 1. determining a station mode according to a motion range of the electromagnetic radiation source; 2. determining a working domain of a point source array according to a position parameter of a motion track of the electromagnetic radiation source; 3. controlling an equivalent construction of the position parameter of the electromagnetic radiation source in an angular domain; 4. controlling the equivalent construction of a distanceparameter of the electromagnetic radiation source in the angular domain. The invention utilizes the equivalent simulation method for the motion characteristic of the electromagnetic radiation sourceto make the research, evaluation and confrontation test of electronic countermeasures such as radar and jammer more efficient and accurate. According to the equivalent simulation method for the motioncharacteristic of the electromagnetic radiation source, a high cost test mode utilizing a aircraft avionics pod is avoided, thereby saving a lot of manpower, material resources and financial. A control blind area is avoided by using a point source station method of a crossover station, so that an equivalent target echo direction can change in a 360-degree range. The performance evaluation of multiple electromagnetic radiation sources can be performed in parallel, thereby improving the test efficiency, saving the test time, and shortening the test period.
