Obstacles avoidance system processing unit for UAV radar. In system for obstacles detection there are tasks which are better handled by FPGA devices and some by regular CPUs. For this system both technologies were connected (figure below). Digital signal processing and control functions for radar unit were performed by small FPGA (Spartan 3DSP). This allows to use more processing expensive algorithms as preprocessing phase for ARM based board. CPU was responsible for communication over a CAN with airplane systems and for more sophisticated algorithms like terrain mapping and flight command processing.
