The widely used superheterodyne radar receivers suffer from the spurious interference severely.An analysis of EMC is given by using the ADS to present the behavioral model of the radar receiver,with focus on the most severe image interference.The S parameter and the spectrum are analyzed.The methods of the EMC reinforcement are given based on the simulation results.The improved receiver is simulated under the same conditions.The results show that the IRR (image rejection ratio) increases and the overall performance of the receiver is improved,providing an efficient method for the pre-evaluation of a receiver with good performance.

Key words: radar receiver;EMC;image interference;ADS
