Abstract :
The authors present a principle of synthetic aperture FM-CW (frequency-modulation continuous wave) radar and show the detection results at several objects in natural snowpack by an FM-CW radar. By incorporating the synthetic aperture technique, it was possible for the FM-CW radar to obtain images with high resolution in the azimuth direction in the snowpack. An averaging and subtracting processing technique is employed to make the synthetic aperture image clear, suppressing the clutter which is characteristic of the natural snowpack structure. From the experiment, this imaging FM-CW radar seems to have a potential ability to map objects embedded in a lossy medium.<>
