Abstract
The invention discloses a multi-frequency point dynamic zero-searching method and system for radome line-of-sight error testing. The method includes: the main control computer controls the movement of the turntable equipped with the receiving antenna to the zero position through the scanning frame turntable controller, and controls the scanning The gantry moves the transmitting antenna to the calibrated position, so that the receiving and transmitting antennas are geometrically aligned; the main control computer controls the travel set by the scanning gantry through the scanning gantry turntable controller according to the set test parameters to obtain the difference channel pattern of the receiving antenna, and then controls The scanning gantry moves the transmitting antenna to the zero-depth position corresponding to the center frequency point to achieve electrical axis alignment; the main control computer respectively obtains the zero-depth positions of all frequency points at all angles under the test without a cover and the test with a cover, and calculates each frequency point at each angle radome line-of-sight error.
Description
technical field [0001] The invention belongs to the technical field of missileradome 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 missileweapon 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...
