Research on Electromagnetic Compatibility of TR Component of Active Phased Array Radar
As a key component of active phased array radar, TR module is developing towards miniaturization and in-tegration. The complex internal and external electromagnetic environment of TR module is analyzed according to its working principle and composition. For the electromagnetic interference problems inside and outside the TR module, different solutions are provided. An example of the abnormal working situation of the radar system caused by the LC loop resonance problem of the TR module in the process of the radar system directional diagram test is given, and an effective mechanism analysis is carried out. And through simple remedial measures, the LC resonance frequency is cleverly avoided, and the electromagnetic compatibility problem of the TR module is solved, which has certain guid-ing significance for the electromagnetic compatibility design of the TR module of the radar system.
