Japanese Patent JPH0122913
Kind Code:
B2
Abstract:
PURPOSE:To obtain the reproducing image with the processing in a short time, by storing the data through the change of rotating position of antenna and processing spectral beam. CONSTITUTION:The antenna 1 transmits the microwave from the transmitter 2 via the circulator 3, receives the reflected wave from the objective and transmits it to the amplitude and phase discriminator 4. The discriminator 4 compares the amplitude and phase of the reception and transmission waves, and the compared data obtained according to the rotation of the antenna 1 is stored sequentially in the contoller 5. The light of the light source 6 is amplitude-modulated 7 at the reproduction section to obtain (m) pieces of spectral beams at the prism 8 to corresponds them to the rotating position of the antenna 1, and it is collected to the reproduced origin S via the amplitude variable device 9, phase variable device 10, beam deflector 11 and amplitude phase compensator 12. Further, the picture of objective is reproduced on the screen 13.
