METHOD OF CORRECTING LINEAR AND ANGULAR COORDINATES OF HELMET OF AIRCRAFT OPERATOR AND ULTRASONIC HELMET-MOUNTED SYSTEM THEREFOR |
摘要 |
FIELD: radio engineering, communication.SUBSTANCE: four helmet-mounted ultrasonic receivers are mounted at reference points on an operator's helmet, and four ultrasonic radiators are mounted in the cockpit above the operator's helmet in the bound coordinate system of the cockpit. Four ultrasonic receivers of four correcting channels are mounted at the edges of the working area of possible helmet positions. Pulsed ultrasonic signals are transmitted and received. The delay time of signals from each ultrasonic radiator to each helmet-mounted ultrasonic receiver and to four ultrasonic receivers of correcting channels is measured. Direction is determined based on the data of said correcting channels.EFFECT: high accuracy of determining coordinates of an operator's helmet in vibration conditions and varying external conditions.2 cl, 4 dwg |
