Abstract :
This paper presents a design of a Radar Signal Generator (RSG) for radar receivers testing and development (i.e. receiver dynamic measurement, pulse compression modules). RSG is a multifunction flexible radar signal source generating multichannel coherent signals with reference signal for radar station and the other auxiliary signals and noise signal. The presented design is based on digital synthesizers with high flexibility in radar signal intrapulse modulation schemes. The architecture of RSG allows complex signals generating with bandwidth up to 150MHz (the frequency range is limited with proper filters due to most used frequency ranges). Phase stability of the output signal is less 1º deviation RMS and phase noise performance of reference signals is -134dBc/Hz@1kHz for 10MHz.
