Design based on MCU for the echo simulator of the range extended target

It is important for the high resolution radar to design the simulator for generating the echoes of the range extended target. In this paper, a simulator design which is based on Micro Controller Unit (MCU) is proposed for generating the echoes of the range extended target. Because those echoes change rapidly and the corresponding period is longer, the high speed FIFO is selected as the data cache. In the idle time of system, waveform data is transferred from MCU to FIFO, whereas in the operating time of system it is transferred from FIFO to D/A converter at a high speed in order to output the waveform. The experimental results show the design can meet the purpose of the echo simulator of range extended target.
