Multiple‐input multiple‐output (MIMO) imaging radar is a new kind of new imaging radar in recent years. It can achieve faster data acquisition speed than the traditional ground‐based SAR due to the ability to get a large number of multi‐channel data in a short period of time. However, traditional single‐core digital signal processors (DSPs) have limited space and ability to deal with such large amount of data. To solve this problem, a real‐time image processing software architecture for MIMO imaging radar algorithm is designed and carried out based on TMS320C6678 DSP of Texas Instruments (TI), which is the highest‐performance fixed/floating‐point DSP based on TI's KeyStone multicore architecture. The efficient imaging algorithms mapping from Matlab to DSP is realised, with efficient task allocation, resource reuse of echo data, and processing variable, and using the method of multicore parallel processing.
