Patent ID: 7928901

Claim:
A system for producing radar images, comprising: a transmitter operative to transmit a pulsed signal; a receiver operative to sample the pulsed signal after reflection; a Doppler-shifting mechanism operative to create a Doppler shift in the pulsed signal; a platform upon which the transmitter and the Doppler-shifting mechanism are mounted, the Doppler shift being associated with relative motion between the Doppler-shifting mechanism and the platform, further comprising an imaging unit operative to receive information corresponding to a plurality of samples from the receiver, determine respective frequency responses for the plurality of samples, and correlate the frequency responses into points on an illuminated target in order to produce an image, wherein the platform is stationary during transmission of the pulsed signal, wherein the Doppler-shifting mechanism is operative to rotate the transmitter with respect to azimuth, wherein the Doppler-shifting mechanism is operative to vibrate the transmitter and; wherein the transmitter is operative such that the pulsed signal is timed to coincide with a peak in a vibration imparted to the transmitter.
