(Paper to be submitted to The Astrophysical Journal)

A first solar radar experiment in microwaves has been carried out with the 300 m dish in Arecibo. *The goal was to scatter the radio waves at 2380 MHz on coronal Langmuir waves in the range from 170 to 270 MHz. The nonlinear interaction of these two wave modes produce a radio signal in backward direction at the beat frequencies

Receiption was at 2600 MHz with a bandwidth of 100 MHz. The transmitter of 250 kW power was pulsed in periods between 0.5 and 1.5 s. The received flux was Fourier analysed and searched for the transmitter period.
