Abstract:
The micro-Doppler m-D effect appears in the synthetic aperture radar SARinverse SARISAR image of a target whenever the target has one or more rotating or vibrating parts. M-D effect introduces distortion in the SARISAR images. On the other hand, m-D effect also carries information about the features of moving parts of a stationary or moving target that can be used for target identification purpose. Based on L-statistics, spectrogram, and inverse Radon transform, a radar data exploitation Matlab toolbox was developed for classifying air, land and ocean targets, which helps Geospatial Intelligence GEOINT support to Canadian Forces. This toolbox will scan and search any M-D activity in the desired area of the SARISAR image. The toolbox has three options 1 Focus the stationary target if there is no m-D, 2 Focus the target after removing the m-D, and 3 extract the m-D and determine the motion parameters. The toolbox was tested and validated against a variety of simulated and measured targets.
