Title: Method and device for determining relative bearing using the TACAN signal, and radionavigation system implementing the method
Inventor: ALAIN MARCUARD
IPC: G01S1/48
Filed: 1992-02-07
Abstract: The invention relates to radionavigation by determining the relative bearing formed by the azimuth angle of a rotating TACAN radio beacon and using the signal emitted by this radio beacon. The signal emitted by a TACAN radio beacon consists of pulses (J) whose arrival is random with respect to the clock in the receiver. The TACAN angle, representing the relative bearing of the TACAN radio beacon, is calculated by processing the envelope of these pulses. This envelope is determined by means of regularly distributed fictitious pulses (E, E2, E3, ...) whose amplitude is the mean of the amplitudes of the two bearing signal pulses situated nearest the fictitious pulse in question on either side of this fictitious pulse. Application to TACAN radionavigation systems.
