Description
technical field [0001] The invention relates to the field of digital signal processing, in particular to an FPGA-based radar signal exchange routing system and a design method thereof, which is applicable to various radar signal processors with FPGA as the data control core. Background technique [0002] In high-speed real-time signal processing systems, especially in radar signal processors, the number of data objects involved is constantly increasing. For example, in synthetic aperture radar, in order to complete complex SAR imaging tasks, it is necessary to involve analog-digital (AD) data, imaging Instructions, imaging data, beam control instructions, beam status information, radar parameter information, GPS information and other data objects of different types and even different interfaces, so how to realize the exchange routing of different data objects becomes particularly important. [0003] FPGA (Field Programmable Gate Array) has become the mainstream chip in radar...
