A new technique to process images of under-snow radar with a displaying system of three-dimensional information is proposed and an experiment to display three-dimensional radar images is done with the constructed under-snow radar system. Since the principle of the proposed radar system is holographic imaging radar, a large IC memory system of 256 K byte, which corresponds to 128 × 128 × 128 boxcels, is constructed to store hologram data and reconstructed images, where each memory cell of 128 × 128 pixcels has 7 bits data corresponding to 128 gray levels of depth information. An experiment to display radar images of the burried objects in snow is done using X-band microwave. Improvement of resolution of images of under-snow radar is also discussed using the constructed dispaying system.
