1. 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; and
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.

18. A method of producing radar images, comprising:
-
transmitting a Doppler-shifted pulse; receiving the Doppler-shifted pulse as a terrain reflection; analyzing the pulse received to generate a plurality of samples; correlating the samples with range bins based on times received; determining the frequency spectrum of for samples within the range bins; and correlating the frequency spectra and the range bins with points on the terrain to produce an image of the terrain. - View Dependent Claims (19, 20)
