Adaptive optimal array detection of targets of unknown spatial location

A primary reason that much attention has been given to array antenna systems is their ability to perform rapid inertialess scanning.[1][2] Despite this great interest in array processing,[3]-[6] the concept of an overall Bayesian approach to the scanning-detection problem has attracted little attention.[7] Classically "beams" are pointed at discrete spatial locations and detection decisions made on a local basis. Other suggested solutions include several non-parametric approaches[8]-[10] and a generalized likelihood ratio approach.[11]
