METHOD OF HEIGHT, AIRCRAFT ACTUAL VELOCITY AND AIRCRAFT VELOCITY VECTOR INCLINATION MEASUREMENT IN RELATION TO HORIZON, ON-BOARD RADAR DEVICE USING METHOD Russian patent published in 2018 - IPC G01S13/42 

FIELD: measuring equipment.

SUBSTANCE: one carries out the earth's surface sensing by virtue of the radar impulse in the direction of the AC roll axis, the reflected signal coherent reception with the acquisition of the two-dimensional radar image (RI) of the terrain in coordinates range-doppler frequency, the finding of the maximum doppler frequency (MDF) on range dependence according to the data of the RI, the generation of the original hypothesis on the AC coordinates due to the available aprior data, upon that, one iteratively specifies the hypothesis on the measurable parameters value by means of the MDF hypothetical curve design, which corresponds to the hypothesis, generates the error signal of the MDF hypothetical curve towards the MDF curve according to the RI data, converts the MDF curve error signal into the measurable parameters error signal, summarizes it with the specified hypothesis, repeats the cycles and returns to the consumer in tracking the measured height, actual velocity and AC velocity vector inclination angle parameters in relation to horizon.

EFFECT: measurement of the height, actual velocity and angle between the velocity vector direction and the horizontal plane when using the system, which is oriented in the direction that is in coincidence with the aircraft roll axis, with the help of the single-beam antenna.
