Polar format Polar format processing based moving target detection apparatus and method in bistatic ground-to-air radar environment

摘要

The present invention discloses an apparatus and method for detecting a moving target in a bistatic surface-to-air radar environment by polar format processing. According to an embodiment of the present invention, an apparatus for detecting a moving target in a bistatic surface-to-air radar environment in which a transmission radar and a plurality of reception radars are separated, the position coordinates of the transmission radar and the plurality of reception radars, the center coordinates of the detection area A parameter storage unit for storing the data; A function acquiring unit acquiring function information through a Fourier transform of a reception signal received by each of the plurality of reception radars and a transmission pulse of the transmission radar; A spatial spectrum calculator configured to calculate a spatial spectrum of a scattering point reflection coefficient using the acquired function information, the location coordinates, and the center coordinates of the detection area; An interpolation unit for interpolating after shifting the spatial spectrum of the scattering point reflection coefficient to a baseband; And a two-dimensional inverse Fourier transform unit that converts the interpolated data into a two-dimensional inverse Fourier to obtain an image of a moving target.
