Research and implementation ranging method based of continuous wave radar on tri-frequency

In the traditional dual-frequency radar ranging system, there is a contradiction between ranging precision and ranging distance. So a tri-frequency ranging method is proposed. The principle of the tri-frequency ranging is that the distance can be achieved by transmitting the three frequencies and then measuring the three phase difference and calculating the number of wavelength. What＇ s more, range ambiguity will not occur within a certain distance. The experimental results show that, if the waveband is 0.47 -0.57m, the measurement of unambiguous distance of 25 -500m can be realized. If the wavelength tolerance error is less than ± 10^-7 and the phase error is less than ± 10 ^-3, the precision of the distance ranging can reach 10^-6.
