Abstract
A system and method for obtaining the bearing angle of radio frequency is utilized in a direction finding system to determine the signal of interest. The system utilized an adaptive interferometric processor to null out modulation occurring due to commutation between the antenna elements. Through this system the bearing angle can be determined accurately and efficiently.
