FIELD: radar technologies.
SUBSTANCE: inventions relate to the field of radar and can be used in radar stations to measure the angle of location of low-altitude targets in conditions of multipath propagation of the probing and reflected signal from the target. Measurement of the angle of the low-altitude target is carried out using three identical, spaced in height, horizontally directed lower, middle and upper receiving antennas. In this case, at the outputs of the lower and middle antennas and at the outputs of the middle and upper antennas, the differences in the complex amplitudes of the signal voltages are measured, the modules of the received difference signals are isolated and the angle of the target location is determined from them.
EFFECT: increased accuracy of measuring the angle of the low-altitude target in the conditions of multipath propagation of the probing and reflected signal from the target.
