Abstract
With the development of digital signal processing and synthetic aperture radar (SAR) imaging algorithms, high-resolution and quick real-time imaging of SAR is required higher and higher. In this paper, the multicore digital signal processor multicore DSP is used to design the spotlight imaging system. The task division and optimization design of each processing node on the board are described in detail, and an online test method based on pseudo-random number is proposed. Real-time processing image is obtained on airborne platform, which verified the feasibility and effectiveness of the imaging system.
