Aligning data across range cells, crucial for high resolution. Azimuth Compression:

In the realm of remote sensing, few technologies have revolutionized Earth observation as profoundly as . Unlike optical sensors that passively record sunlight, SAR actively illuminates the Earth’s surface with microwave pulses, penetrating clouds, rain, and even vegetation canopies. However, the raw data recorded by a SAR sensor is unintelligible to the human eye. It resembles nothing more than random noise. The magic lies in the digital processing .
