| titleOfInvention | Arrangement for receiving TACAN signals |
| abstract | A receiver for pulse amplitude modulated TACAN signals having 15 Hz and 135 Hz modulating components and which determines the TACAN bearing angle by calculating the phase shift angles phi 15 and phi 135 of those components of the received signals. The amplitudes of the received pulses and their times of arrival over a given time interval are stored in a memory. From such stored values a microprocessor determines the elements of a column vector Z defined by the pulse amplitudes and arrival times, and the elements of a matrix M defined by the arrival times. A column vector X corresponding to M-1.Z is calculated, the elements of which are trignometric functions of phi 15 and phi 135, from which those phase shift angles are determined. The TACAN bearing angle is then evaluated from the phase shift angles without requiring circuits to phase lock them with respect to each other. |
