| Abstract: | A system which is used to acquire and replay radar＇s intermediate/video-frequency data, is designed in this pa- per. The system uses FPGA as kernel chip to control the data acquisition and transmission, and uses USB2.0 to communicate with a microcomputer. With the help of virtual technology, it adopts Visual C-- language to design a real-time display inter- face on microcomputer monitor. In the process of design, the FPGA devices were programmed with VHDL language. Along with the input signal＇s acquisition and recording, the system also realized the {unction of anti-dithering, zero-detection, frequency measurement, and the peak value, maximum to maximum and average voltage measurement. The system which is put into a small shielding box, is very portable, and it is very convenient to acquire the data of outside radar. |
