Calculation Method for High-Resolution Range Рrofiles of Complex Shape Radar Objects

The high-frequency approximation of the pulse characteristic is calculated as a response of a radar object of complex shape to a short pulse, all the energy of which is concentrated near some frequency. The high-resolution range profiles are obtained with the convolution operation of the calculated high-frequency approximation of pulse characteristic and the sounding signal, all the energy of which is also concentrated near the same frequency. The calculated high-resolution range profiles are compared with the profiles obtained by inverse Fourier transform from the frequency response of considered object. The calculation time gain of the proposed approach in comparison with the classical one is estimated.
