Doppler Simulator Realization Based on Digital Synthesis Technology
Huang Zhi-wang · Modern Radar · 2005
The realization methods of a Doppler simulator which is employed in an airborne fire-control radar for CW guided missile testing and tuning are described in this article. The effects of replacing traditional analog method with digital synthesis technology are given. Then a reasonable scheme for digital synthesis obtained from the performance comparison of frequency precision、stability and harmonic suppression. The digital synthesis technology can also increase work efficiency and be useful for batch production because of application of large scale integrated circuits and programmable components.
