ABSTRACT:
This invention discloses a DME which employes an improved technique for validating received replies. The technique employed reduces lock-on time by analyzing all of the range data received within a set time period following the transmission of an interrogation pulse pair rather than just one range figure for each interrogation cycle. The DME also provides improved accuracy and reliability by varying the width of the range gate used in analyzing the received range data in accordance with the time difference between the two interrogation cycles from which range data is being compared with system status, i.e., whether the system is in the locked position or not.
