Method for realizing arbitrary track simulation of radar

The invention belongs to the field of radar electronic countermeasure and hardware-in-the-loop simulation, and in particular relates to a method for realizing arbitrary track simulation of conventional radar. The method specifically comprises the following steps: (S1) initializing an arbitrary track simulation hardware system and setting parameters; (S2) setting the track of a to-be-simulated target on a radar P display interface simulated by a host computer; (S3) reckoning the state of the to-be-simulated target; (S4) detecting a radar signal, obtaining the amplitude, frequency, pulse width,repetition period and antenna scanning period of the radar signal; (S5) intercepting the radar signal and judging whether the radar signal irradiates the to-be-simulated target according to the intercepted radar signal and a preset difference tolerance value; (S6) modulating and forwarding the signal; (S7) the track simulation entering the next time and carrying out repeated running until the endof a track simulation proc
