Abstract : An apparatus and method is capable of acquiring useful three-dimensional radar images from an aircraft which travels in a curvilinear path to generate only a sparsely filled synthetic array. A motion measurement unit outputs position measurements as the aircraft travels in the curvilinear path. The system includes a motion compensation and timing unit and a wave transmitter which outputs chirped radar signals. An antenna coupled to the wave generator sends the chirped radar signals to a region to be imaged and receives scattered chirped radar return signals from scatterers in the region. (AN)
