“…This means that the SNR only can't be used as a best way of selecting the suitable windowing category, but other factors should be taken into account, for any SAR system. On the other hand, the MIMO technique has been introduced in [9]. This technique improves the SAR image but, it requires high resources and its hardware is complex.…”

Synthetic aperture radar (SAR) is an imaging device mounted on a moving platform. Its ability to identify a weak target from a nearby strong one depends upon the peak side lobe ratio (PSLR). This paper is intended to ameliorate such important ratio through the use of windowing of the transmitted pulse and studying the noise sensitivity of the resulted image. Two experiments are simulated for different types of windows using point target and earth images. PSLR, dynamic range, spatial resolution, radiometric resolution, mean and standard deviation are evaluated for each window of the point target image. Also, the sensitivity to noise is discussed through the calculation of the mean square error, root mean square error, signal-to-noise ratio (SNR), peak SNR for the earth image. Experimental results show that Triangular, Gaussian and Hann achieve the highest PSLR performance with different reductions in their resolution, whilst Taylor has the worst performance due to its high sensitivity to noise. The remaining ones give intermediate performance.
