🔥 Content Introduction
1. Research Background
Synthetic Aperture Radar (SAR) is a high-resolution, all-weather microwave remote sensing imaging technology that plays an irreplaceable role in various fields such as terrain mapping, disaster monitoring, military reconnaissance, and ocean observation. With the continuous development of SAR technology, new systems and algorithms are emerging, leading to an increasing demand for research and optimization of its imaging performance. Through radar SAR imaging simulation, the effectiveness of imaging algorithms can be quickly verified without relying on actual flight tests, allowing for analysis of how system parameters affect imaging quality, reducing R&D costs and risks, and providing strong support for the design, optimization, and application of SAR systems. Therefore, conducting research on radar SAR imaging simulation has significant theoretical significance and practical application value.
2. SAR Imaging Principle
SAR utilizes the relative motion between the radar and the target, employing signal processing techniques to equivalently treat a small aperture antenna as a large aperture antenna, thereby achieving high azimuth resolution; in the range direction, it relies on transmitting wideband signals and using pulse compression techniques to achieve high resolution. Specifically, the radar emits a series of pulse signals towards the target area during its motion, and the signals reflect back to the radar after encountering the target. The echo signals contain information about the target’s distance, azimuth, scattering characteristics, etc. By performing a series of complex signal processing operations such as range migration correction and azimuth focusing on the echo signals, a high-resolution SAR image is ultimately formed.
