Abstract

PURPOSE:To enable accurate distance measurement over a wide variety of range for the objective having the plane not flat, by projecting microwaves on the objective as circular polarized waves and receiving them. CONSTITUTION:The microwaves from the generator 13 are frequency modulated at the triangle wave signal at the generator 12, and fed to the antenna 31 in the form of straight line detection continuously, and radiated to the objective 22 from the cone type horn 36 through the conversion 35 into right swing circular polarized waves. Further, the reflected waves from the objective 22, are received on the antenna 32 as the ellipse polarized waves, converted into straight line polarized waves at the left swing circular polarized wave converted 36 via the cone horn 37, and fed to the mixer 17. The mixer 17 mixes the reception waves with the transmission waves from the generator 13, picks up the beat signal and feeds it to the signal processor 23. The processor 23 produces the distance data according to the clock of the oscillator 11 from the best signal and feeds it to the display 24.
