Abstract :
A research project with the experimental phase-array system ELRA is discussed with respect to the extended and improved possibilities for performing measurements and evaluations for different types of radar operation. The variability of waveforms for solid-state transmitters is described. Flexible control of multifunction operation with various search and localization tasks is achieved with a network of microcomputers. Different means of signal processing are used for target detection and estimation. The active receiving array is divided into subarrays and has digital beamforming for pattern shaping and adaptive jammer suppression. Experimental results are presented for illustration
