Radar-Like Measurements with an Experimental Digital Beamforming Array Antenna
1998 (English)Conference paper (Refereed)
An experimental S-band digital beamforming receiving array antenna has been used in “radar- like” measurements, where radar signals with programmable waveforms are transmitted. The measurements are carried out in an anechoic chamber and the measured signals come from the direct path from transmitter antennas to the receiver antenna. In this way targets are simulated. On the received signals, conventional beamforming, pulse compression, doppler filtering and high resolution direction of arrival estimation are performed. Accurate channel calibration and channel equalization are utilized. This paper first describes the receiving antenna, transmitter control, measurement arrangements, calibration and signal processing. It then presents some measurement results for high resolution direction of arrival estimation and for radar resolution of one and two targets.
