The implementation of space-time adaptive processing (STAP) system includes the allocation of system tasks, communication and storage of mass data, parallelism, mapping and scheduling of algorithm modules. Concerning for the problem that data communication in real time system is of multi-layer and multi-rate data transmission between various nodes, this paper studies the communication planning between various tasks in implementation of heterogeneous STAP system, discusses the influences of different communication configuration layer on data communication, and realizes a four-channel STAP system based on a coarse-grained task model. Experimental results indicate that the planned data communication scheme could meet the demand of system real time processing.
