Adaptive control and tracking with the ELRA phased array radar experimental system
Abstract
The Electronically steered Radar (ELRA) is employed as an experimental system to identify and analyze problems of phased array technology. The system configuration is examined, taking into account the antenna, the hard-wire logic, the process computer, the central computer, a display/dialogprocessor, and the displays. Adaptive search patterns are considered along with aspects of target individual tracking, and the software structure for multitarget tracking. The first track was obtained with the system in 1976. The target was a cargo helicopter CH53 and the antenna had about 20% of the planned number of elements. At the track initiation the estimated velocity vector shows great variances which are reduced by Kalman filtering after the initiati
