EMI Analysis for Two Types of Radar on the Same Platform

On limited space of the same platform, more and more radio electronic equipment are increased, which results in more problems of electromagnetic compatibility(EMC) that almost all of them caused by antenna mutual-coupling. As the example of two radar on the same platform, this paper gives the EMC test data in each carrier frequency band. Through the test data analysis it can be concluded that the electromagnetic interference (EMI) caused by adjacent frequency channel interference, According to the results of spectrum measurement, when increasing the carrier frequency interval it can ensure the two radar works well compatibility.
