Abstract
Systems and methods for measuring wind speed and direction in clear air conditions using a wide band Doppler radar in accordance with embodiments of the invention are disclosed. In one embodiment of the invention, a wide band Doppler radar system includes an antenna assembly includes at least one transmit antenna and at least one receive antenna; a transceiver connected to the antenna assembly configured to transmit a radar beam includes a transmit signal on a Ka-band carrier frequency and receive a backscattered radar beam includes a carrier frequency that is frequency shifted relative to the transmitted Ka-band carrier frequency of the backscattered radar beam; a data acquisition system connected to the transceiver configured to estimate a wind velocity vector by calculating a Doppler shift between at least one transmitted radar beam and at least one received backscattered radar beam.
