There are several improved designs of passive radar reflector available, but their performance is ultimately limited by the cross-section area and this is governed by the size of the buoy and the acceptable windage. Therefore it is needed to investigate the low-cost, low power, a active device that can be improve the reliability of response. Active Radar Reflector(AAR) consists of a microwave amplifier with separate receive and transmit antennas. It is a device which automatically transmits a signal in response to an interrogating signal received. It was intended to improve the consistency of the radar return from the buoy and the small craft, particularly in poor sea conditions. And it directly improves safety of navigation at sea.
