Measure and Predict the Receiver's Electromagnetic Susceptibility Fast

Evaluating and predicting rapidly and accurately a high sensitivity receiver's adaptability in complex electromagnetic environments is a tough job. To solve this problem, a novel testing and prediction method based on dual-channel multi-frequency is proposed to improve the traditional two-tone test. An experiment performed on a radar receiver confirms the reliability of the method proposed in this paper. It shows that the interference of each harmonic frequency and each order to the receiver can be identified and predicted with the sensitivity model. Based on this, fast and comprehensive evaluation and prediction of the receiver's electromagnetic susceptibility in complex environment can be efficiently realized.
