Abstract
The signal modulation of modern high-resolution wideband Radar requires diverse and flexible mode for adapting variety complex environments. The serial communication of single-chip microcomputer was used for receiv⁃ing commands,DDS and RF phase modulator was configured by FPGA. A Radar signal modulation module was real⁃ized,which supported continuous wave and pulse frequency or phase modulation. The technical problems were solved in the pulse FM synchronization by code control. Entire modulation module carrier center frequency was 1.6 GHz,FM waveforms had positive and negative sawtooth and triangular wave,frequency modulation bandwidth was up to 600 MHz,the phase modulation sequences had Barker codes,pseudo-code L and M series. The test result indi⁃cated that the system output signal had a stable performance and a high reliability.关键词
