We have used the VLA to make images of the planets which are continuously illuminated by the high power planetary radar transmitter on the 70 meter antenna at Goldstone, CA. That instrument is capable of transmitting up to 460,000 watts of continuous power near 8.5 GHz. Radar imaging experiments became possible after the installation of the 8.5 GHz receivers on all VLA antennas by NASA for the encounter of the Voyager spacecraft with Uranus. A similar radar may be configured with the Australia Telescope (array) at Narrabri and the Goldstone 70 m at S-band which may be important for experiments on Venus whose atmosphere strongly absorbs at X-band. Highly successful experiments have been carried out at the VLA on Mercury, Venus, Mars, Saturn's rings and Titan, the giant satellite of Saturn.
