| titleOfInvention | High-precision ranging and verifying system and method |
| abstract | The invention discloses a high-precision ranging and verifying system and method. A verifying system comprises an optical part and a translation platform, wherein the optical part comprises a laser, a photoelectric modulator, a light intensity amplifier, a photoelectric demodulator, and optical fibers for connecting all the devices and is used for simulating a spatial remote distance; and the translation platform comprises a controller, a moving platform, a fixed platform and a screw rod as well as a transmitting antenna and a receiving antenna which are respectively arranged on the moving platform and the fixed platform, and the translation platform is used for realizing adjustment of accurate space distance. According to the high-precision ranging and verifying system and method, the transmission distances before and after moving are sampled through adjusting a distance between the moving platform and the fixed platform, the stability of a ranging system is obtained by calculating the mean-square deviation of the sampled data, and the ranging precision of the ranging system is obtained by comparing the average value of the sampled data and comparing the average value of the sampled data with the actual moving distance of the moving platform. According to the invention, the superiority of optical fiber communication is fully utilized, hundreds of kilometers of space distance is simulated, the interference from external environment is shielded, and the stability and precision of the ranging system are effectively verified. |
