Main Article Content
Abstract
Big data real time processing and robust data transmitting are the major requirements to modern telemetry data transfer hardware. In this paper SAR data processing algorithms such as compression, data packet generation, synchronization and jam-free coding for noisy communication channel and data recovery on receiving side with following radio image focusing are modelled. Structure diagram was implemented in MatLab. Raw data ERS-1 was used as input data. Modified entropy-constrained block adaptive quantization algorithm was used for compression. Noise immunity coding based on Reid-Solomon codes. Radar images based on recovered SAR data with various noise levels are presented.
