Abstract : An improved imaging system has applications to synthetic aperture radar, inverse synthetic aperture radar, delay-doppler radar, positron-emission topography sonar, radiometry and other applications having a target image provided by a series of data parameterized by a variable such as theta. A receiver structure includes a band-pass matched-filter, square law envelope-detector, specialized processing and convolving to produce the improved images irrespective that the radar signals have practical side lobe structures and other features. Despite the demands of specialized processing the architecture of the algorithm permits real-time implementations. Patent. (rh)
