EMC Aspects of Phased Array Radars with Multiple Final Amplifiers

Abstract

EMC ASPECTS OF PHASED ARRAY RADARS WITH MULTIPLE FINAL AMPLIFIERS L Lieb, ECAC, Annapolis, MD. Corporate feed phased array radars with multiple final ampli­ fiers have certain unique characteristics which affect their EMC performance. These characteristics present special problems in defining and performing measurements required by military and civilian standards. The frequency-dependence of the mainbeam direction and multiple spurious emission patterns must be con­ sidered when assessing compliancy with MIL-STD-469. The problems encountered in proving the compliance of phased arrays with multiple final amplifiers are discussed.
