Analysis and Calibration of Direction Finding Error of Array Antenna Caused by Random Vibration
摘要
Abstract
To solve the direction finding error of array antenna due to vibrator displacement caused by low frequency random mechanical vibration of ship deck,a model of antenna vibrator' s random vibration error is established. The effect of random vibration modes of the antenna array on angular receiving signals in three axial directions is simulated and analyzed,and a calibration method is presented for angle-measuring error is presented based on simultaneous measurement by several receivers on several different positions. Several er-ror calibration vectors are obtained with this method by using the least square method. By compensating the error using the calibration vector of the antenna beam pointing into the sector,it has solved the calibration problem for angle-measuring error of array antenna under the mode of low frequency random vibration. This method has been applied in data resolution of ship-borne microwave landing guidance system.关键词
