METHOD FOR SCANNING UNDERLYING SURFACE ALONG COURSE Russian patent published in 2021 - IPC G01C15/00 

FIELD: instrumentation.

SUBSTANCE: invention relates to the field of instrumentation. The method for scanning the underlying surface along the course consists in registering measuring information from a strapdown inertial navigation system, an optoelectronic system, and a radio altimeter installed on the aircraft. In this case, an array of data is formed, including the ground speed, the height of the aircraft, the elevation angle and the azimuth angle of the optoelectronic system. The values for the field of view of the optoelectronic system are set. Next, the measurement information is processed: first, the rotation parameters of the optoelectronic system are manually set: the angle of rotation according to the azimuth angle and the angle of the place. Then the values of the angles necessary for calculating the maximum scanning span of the optoelectronic system are calculated, and the value of the maximum scanning span of the optoelectronic system and the scanning speed of the optoelectronic system are calculated. Next, the vector of the line of sight is rotated along the azimuth with a given scanning speed when adjusting the angular velocities of the azimuth angle and the elevation to which the vector of the line of sight should be rotated, using an angular contour.

EFFECT: increase accuracy of scanning due to the use of an adaptive approach in determining the scanning parameters.
