Abstract :
An active radar calibrator (ARC), consisting of a receive-antenna and a transmit-antenna, with an RF amplifier in between, is proposed as a tool for conducting high-precision calibration measurements of radar systems. The ARC can be designed to have a large radar cross section and a broad pattern. Its major advantages over passive reflectors are its small physical size and its suitability for calibrating radars that operate in any polarization configuration.
