Abstract :
In PN-code continuous wave multi-baseline interferometer angle-measuring radar system, one of the important issues for angle-measuring is to calibrate the antenna array receiving channels phase time-varying delay inconsistency. This study is proposed through assisted broadband spread spectrum calibration sources for interferometer antenna array receiving channel increasing phase inconsistency real-time active calibration method. The computer simulation shows that this method has higher precision phase calibration.
