- Abstract
An image formation method of passive synthetic aperture radar applied by FPGA programming is proposed. In the radar system, GNSS satellite is employed as the transmitter, while the receiver is fixed on the earth ground. The radar antenna points to a nearby field. The imaging formation is achieved by applying back - projection algorithm on the received radar signal from field of interest. All the work is implemented on the Intel DEI - SOC hardware platform, where a Cortex -A9 and Cyclone V FPGA is consisted of. The Cortex-A9 is taking care of scheduling and controlling, while FPGA is handling data calculation. The whole system benefits from high efficiency by exploiting the strengths of both kinds of chips alter integrating pipeline and parallel processing. The strong data processing capability of FGPA enables it of huge computational task? thereafter solving long -last processing issues. In the end, a real data of GNSS passive radar is processed by using up - mentioned method and platform, the output coincides with our expectation.
