Abstract

Holographic radar of RASCAN type provides an output signal that is amplitude-modulated by the phase variation between transmitted and received signals. In this work RASCAN radar response is compared with a model by several experiments performed in air with a 4GHz probe scanning a planar metallic reflector inclined at different angles. The radar response shows a series of dark and light stripes with spacing dependent on signal frequency and velocity, and reflector inclination angle. The model is used to interpret the amplitude variations as a function of probe position.
