Abstract
In order to measure accurately the instantaneous real speed on the sea, a low cost Doppler radar has been developed in the W-band. The main parts of the device are a Gunn diode oscillator and a Schottky diode mixer integrated on the same printed circuit, on either side of the emission and reception system including a conical horn with a Fresnel zone plate, excited by the dipole antennas of emission and reception. The Doppler signal, which is obtained after mixing, must be in the order of tens of kHz.
