Laser ranging method for enemy aircraft interception and combat system, involves transmitting slope ramp if average of beat frequencies is lesser than total amplitude of modulation
Laser ranging method for enemy aircraft interception and combat system, involves transmitting slope ramp if average of beat frequencies is lesser than total amplitude of modulation
The method involves expressing the distance and radial speed of targets differently based on beat frequencies to define four ambiguity zones. A choice between the zones is made by comparing the frequencies to determine the sign of Doppler frequency. The average of the frequencies is compared with the total amplitude of modulation. A slope ramp is transmitted if the average is lesser than the total amplitude of modulation. An independent claim is also included for a laser ranging device.
