Reflected-beam ranging system

摘要: A reflected-beam ranging system in which echo signals are displayed cartographically on the screen of a color picture tube having at least two components. circuit means, including frequency selective filter means and rectifying for providing pair output whose amplitudes contain Doppler information is connected to each receiver, preferably has plurality outputs one sector field. The mixed mixing applied respective control amplifiers so as display different colors depending content signals. may, example, comprise discriminator rectifier from signal or high-pass low-pass separately rectified provide
