Abstract

The coherent ultra short pulse radar provides high resolution image of the target. A model of this image is the superposition oj the complex envelopes of the signals retunedfrom the point scatterers. The values of the complex envelopes are distributed over radar image coordinate plane in accordance with their positions and reflection coefficients. Radar image model is based on the known radar pulse envelope and a pattern of the antenna. The parameters of the target point scatterers are processed in the frequency domain by using of one dimensional data extracted from the two dimentional FFTofthe radar image.
