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 a device for detecting a moving target in a bistatic ground-to-air radar environment by polar format processing and a method thereof. According to one embodiment of the present invention, provided is the device for detecting a moving target in a bistatic ground-to-air environment in which a transmission radar and a plurality of reception radars are separated. The device for detecting a moving target in a bistatic ground-to-air radar environment by polar format processing comprises: a parameter storage unit storing position coordinates of the transmission radar and the plurality of reception radars, and detection region center coordinates; a function obtaining unit obtaining function information through Fourier transformation of a reception signal received by each of the plurality of reception radars and a transmission pulse of the transmission radar; a spatial spectrum calculation unit calculating a spatial spectrum of a scattering point reflection coefficient using the obtained function information, position coordinates, and detection region center coordinates; an interpolation unit interpolating the spatial spectrum of the scattering point reflection coefficient to a baseband; and a two-dimensional inverse Fourier transformation unit performing two-dimensional inverse Fourier transformation for the interpolated data to obtain an image of the moving target.
