An Analog Open-Loop Adaptive-Array Antenna System [PDF]
IEEE Transactions on Aerospace and Electronic Systems, 1983 A new open-loop adaptive-array system with excellent transient behavior is presented. The system is constructed of analog circuits and determines complex weights without using the feedback of the array output. The performance attainable with the system is described in detail.
