Abstract :
A multi-channel digital receiver architecture is studied and its performance is analyzed for electronic warfare applications. It is found that this architecture has excellent performance for the intrapulse analysis and direction-finding of radar signals. Three unique features are identified: (a) both AOA and intrapulse information can be extracted from the same data set; (b) improvement in the quality of intrapulse information is obtained by a simple averaging of the digitized data profiles from all channels; and (c) since both the AOA and intrapulse information are interrelated, the quality of one parameter can be verified by the other in a multipath environment
