Abstract :
In FM-CW imaging system, there exist various distortions which will decrease the image quality by expressing themselves as pair-echo range lobes. This paper describes a method that corrects the system distortions using only a reference point-like object. The computer simulation and anechoic chamber experimental results are presented to show the effectiveness of this correction method
