Research on Angle Tracking Technology of DS/FH Communication System

摘要：

　　The direct sequence spread spectrum communication system adopts the coherent demodulation method to acquire the angular error signal at present.However, the carrier frequencies hop continuously in DS/FH communication system, and this system works in the interference environment.It will bring some difficulties to use the coherent demodulation to attain the angular error signal.For this purpose, a new dual-channel monopulse angle tracking algorithm is proposed.This algorithm can apply to dynamic interference environment.The algorithm can realized the angular error signal demodulation and automatic phase calibration under the rapid hopping in carrier frequencies condition.The test results show that this algorithm can effectively demodulate angular error signal under the interference environment, and realize the angle tracking and phase calibration function.
