摘　　要：针对有源相控阵雷达接收通道幅度相位不一致问题,提出了一种K系数校正方法,计算了内源幅相校正系数与外源幅相校正系数的比例因子K,根据内源校正值与K系数的关系,即可获取外源幅相校正值,从应用实现角度简便有效地解决了外场实时幅相校正难的问题,验证了该方法的有效性。Aiming at the problem of amplitude and phase inconsistency in receiving channels of active phased array radar,this paper proposes a K-coefficient calibration method,calculates the scale factor K between the internal and external amplitude and phase calibration coefficients,obtains the external amplitude and phase calibration value according to the relationship between the internal calibration value and the K coefficient,solves the problem of real-time amplitude and phase calibration in outside fields easily and effectively from the perspective of application and realization,verifies the effectiveness of this method.
