. Today, radar imaging with synthetic aperture has obtained an important place in radar remote sensing, in such a way that it is utilized in the variety of space borne, airborne and ground platforms to extract information from different desired surfaces. Among these, Ground Based Synthetic Aperture Radars (GB-SAR) has numerous applications such as space system calibration, change detection, target detection, surface displacement determination and condition monitoring. In general, in GB-SAR systems, given that the power of the transmitted signal is low, the received signal is also of low power, and subsequently the presence of target in the image is of lower probability. Therefore, in this research, a method is proposed to increase the received signal power based on pulse integration by a non-Coherent method which results in an increase in the Signal to Noise Ratio (SNR), thereby increasing the focusing power on the target. In this way, a large number of samples can be received in the data collection section and the gain can be therefore increased by integrating the number of received pulses. According to the −3.22 dB Improvement of focusing evaluation criterion (PSLR), it is shown in this research that the accuracy of the target detection is increased. Finally, the effect of the number of pulses integrated on the noise presence and accuracy of the target detection is described.
