| Abstract: |
| 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 low power, and subsequently the presence of Target appears in the image with a lower probability. Therefore, in this research, a method is proposed to increase the received signal power based on pulsed aggregation 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, we receive a large number of samples in the data collection section and then we increase the gain by aggregation the number of received pulses. According to the focusing evaluation criterion (PSLR), we will increase the accuracy of the target detection. Finally, we describe the effect of the number of pulses aggregated on the accuracy of the target detection. |
