Слайд 1RADIO ALTIMETER

Слайд 2The radio altimeter of small heights RV-3 serves for measuring the

true altitude of a helicopter over surface of land or sea in the range from 0 to 300 m. Alarm height alarms - sound and light is issued at any height in the range from 0 to 300 m.

The radio altimeter of small heights RV-3 serves for measuring the true altitude of a helicopter over

Слайд 3The principle of operation of the radio altimeter is based on

determining the time of passage of the radio signal from the transmitting antenna to the reflecting surface and back to the receiving antenna.

The principle of operation of the radio altimeter is based on determining the time of passage of

Слайд 4There are also ground radio altimeters. They determine the distance to

the aircraft, the speed and direction of its movement. The altimeter control device calculates the angular velocity of the aircraft relative to the station and begins to rotate the antenna of the altimeter with the corresponding speed.

At the same time, the antenna goes up and down, scanning space with a narrow beam. Thus, the angle of the aircraft is calculated. The simplest transformations can determine the height above the ground.
