Radar echoes from the sun The first solar radar echoes were detected by a research group at Stanford University in 1959. Transmitting 40 kW at 25.6 MHz by using an antenna of 3.450 sqm (square meters) aperture, the radar echoes were marginally significant with an integration time of 18 minutes. Regu...
