THREE-DIMENSIONAL DIRECTION FINDING FOR ESTIMATING A GEOLOCATION OF AN EMITTER |
摘要 |
One embodiment of the invention includes a computer readable medium configured to perform a method for determining a three-dimensional geolocation of a terrestrial emitter. The method includes receiving a signal from the emitter at an antenna array. The method also includes determining a three-dimensional line-of-position (LOP) to the emitter based on the signal. The three-dimensional LOP can include an azimuth angle and a depression angle. The method further includes calculating the three-dimensional geolocation of the emitter based on an intersection of the three-dimensional LOP with digital terrain elevation data (DTED) associated with the Earth's surface. |
