Apparatus and method for radar imaging by measuring spatial frequency components

摘要: A radar imaging system is provided that directly measures the spatial frequency components of a scene via digital-beam-forming techniques applied along cross-track dimension. Separate transmit and receive antennas provide increased integration time for function, thus improving signal-to-noise ratio. segmented antenna employed processed as series interferometers sensitive to corresponding separation between pairs elements. Range gating used in along-track dimension divide return from an illuminated swath into multiple range bins may be independently. The provides improved ratio lends significant flexibility image formation process, quality imaging. An embodiment having also enables generation three-dimensional stereoscopic images.
