Summary: | The invention relates to a signal source system and method of realizing short range simulation echo by means of photoelectric conversion. The signal source method of realizing short range simulation echo by means of photoelectric conversion includes the steps: S1, a program control attenuator receives a radiofrequency signal output from a short-range ranging radar system, performs quantitative attenuation, and adjusts the radiofrequency signal power to the range supported by a photoelectric converter; S2, the photoelectric converter converts the attenuated radiofrequency signal into an opticalsignal and performs time delay, and then converts the optical signal after time delay into an echo radiofrequency signal; and S3, the program control attenuator can perform quantitative attenuation on the echo radiofrequency signal, and sends the echo radiofrequency signal to the short-range ranging radar system, wherein a central processing unit switches and controls signal conversion of the photoelectric converter, and |
