Performance evaluation of ultra wideband (UWB) radar in terms of target detection, resolution, recognition, and clutter and interference rejection depends on the structure of the radar waveform. The chirp waveform, which is commonly used in radar applications, has high time sidelobes in the level of − 20 dB. Another limitation is the excessive range-Doppler cross coupling, which occurs, when the Doppler...
A Synthetic aperture radar (SAR) simulator for image quality evaluation is presented. This simulator can be used for the estimation of SAR image quality performance from the simulated raw data using different wideband signals. These signals are random noise, chirp and chirp-Gaussian (proposed) waveforms. In this paper, a mathematical model for these waveforms is introduced. The autocorrelation function,...
