Radar signal simulators （RSS） are becoming the necessary test instruments for the evaluation and commissioning of modern radar systems. Firstly, this paper briefly introduced the key implementation technology of the RSS for airborne high - resolution Pulse Doppler （PD） radar. Secondly, it is proved that the RSS is qualified to be the signal source for a simulation system. Lastly, the RSS is applied to evaluate the performance of the high- resolution PD radar system, in terms of the improved factors of both signal - to - noise and signal - to - clutter of the signal processor. Furthermore, the display interface of radar terminal is evaluated by using the simple test methods addressed in this paper. The experiment results through this simulator demonstrated the high efficiency of the proposed methods.
