Abstract:

The device for measuring the drift angle and flight speed of an aircraft, based on using the Doppler effect with continuous emission and reception of electromagnetic waves on a four-beam antenna. To increase the accuracy of measuring by simultaneous coherent reception of signals reflected from two sections of the terrain and emitted by two beams of the antenna, and to decrease the weight of the apparatus, one receiving channel is used that is equipped with a computer which serves for polar commutation of the receiving antennas and a transformed signal of the transmitter is used as a voltage heterodyne.
