Radio Frequency Simulation of the Target Signal in a Frequency Agile Radar

In this paper,a realization scheme for RF simulation of the target signal in a frequency agile radar is discussed. Applied to hardware-in-the-loop simulation for guidance and control systems, the simulator generates source signals by means of IFM and simulates the angular position of the targets by an aerial array. Measures are taken in the hardware to correct the errors in precision azimuth control of the aerial array caused by frequency agility. The result of the simulation test for the radar seeker indicates that the simulator can work well at a small azimuth and features a high accuracy.
