Abstract

The invention discloses a multi-frequency point dynamic zero-searching method and system for antenna housing line-of-sight error testing. The method comprises the following steps: a master control computer controls a rotary table with a receiving antenna to move to a zero-point location through a scanner rotary table controller, and controls the scanner to move an emitting antenna to a calibrationlocation, so that the receiving antenna and the emitting antenna are in geometric alignment; the master control computer controls the scanner to move with the set travel so as to acquire a differencechannel directional diagram of the receiving antenna through the scanner rotary table controller according to the set testing parameters, and then controls the scanner to move the emitting antenna toa zero-deep location corresponding to a center frequency point, thereby realizing electric axis alignment; and the master control computer acquires the zero-deep locations of all frequency points atall angles under the coverless testing and the covered testing, and then computes the antenna housing line-of-sight error of each frequency point at each angle.

Description

technical field [0001] The invention belongs to the technical field of missile radome testing, in particular to a multi-frequency point dynamic zero-searching method and system for radome line-of-sight error testing. Background technique [0002] The seeker radome is one of the important components of the anti-aircraft missile weapon system. The radome protects the seeker antenna from the interference of unfavorable external environmental factors, but the radome wall will affect the radiation characteristics of the antenna, resulting in electromagnetic wave transmission loss and antenna beam pointing deviation, reducing the operating range and guidance accuracy of the guidance system. The electrical performance test of radome has always been an urgent problem to be solved in the field of radome and microwave measurement. It generally includes two parts: power transfer coefficient test and line-of-sight error test. Among them, the test of line-of-sight error has always been t...
