DESCRIPTION:Previous generations of direction of arrival monopulse architec
 tures employ rectangular arrays whose quad outputs are processed in the mi
 crowave domain to generate three signals from which 2-D angle information 
 is derived. Historically\, such architectures are null-seeking\, which car
 ries the inherent disadvantage that\, the better the alignment of line-of-
 sight of the signal source to monopulse boresight\, the worse is the signa
 l-to-noise ratio (SNR) in the corresponding receiver channels and hence th
 e poorer the estimate of angle error. Increasing use of digitally-generate
 d signals in radar and communication systems offers the opportunity to uti
 lize non-nulling architectures to estimate angle error and employ three no
 n-collinear feeds arranged to estimate direction of arrival. Such triangul
 ar architectures provide smaller variations in SNR than their null-seeking
  counterparts\, offer superior calibration strategies\, and in some cases\
 , simpler alignment of feed hardware.\n\nSpeaker(s): Dr. Brian Sequeira \,
