description: The given work is devoted to reducing the execution time of algorithms for the formation of radar images obtained using a synthetic aperture radar (SAR), and finding optimal parameters of speckle noise reduction filters by the sense of the best quality filtering. Thus, the work consists of two parts, which consider the stages of processing data obtained from SAR.
In the first part of the paper, the issue of reducing the execution time of algorithms for generating radar images through parallel computing is considered. The implemented algorithms are tested on the Jetson TX1 computing platform. Due to the characteristics of Jetson TX1 and the application of the parallel computing method, the formation of radar images can be performed on board unmanned aerial vehicles for terrain mapping.
The second part of the work is devoted to the study of filters of multiplicative speckle noise on radar images. The most commonly used filters are considered, their optimal parameters are found, their operation on images with various features is tested, the best filters for working with radar images are highlighted. The use of these filters will allow the processing of radar images without the influence of speckle noise.
