Embodiment

[0038] Embodiment: the measurement mechanism of fuze antenna: for any antenna, its far-field radiation field can be expressed as:

[0039] E → ( r → ) = u ^ F u ( θ , φ ) e jψ ( θ , φ ) e - jkr r - - - 1 )

[0040] In the formula: F u (θ,φ) is the amplitude pattern function, ψ(θ,φ) is the phase pattern function, is the free space phase shift constant, represents the polarization unit vector at a c...

Abstract

The invention discloses an automatic measuring system and an automatic measuring method of a fuze antenna far field. The system comprises an antenna receiving turntable subsystem, a transmitting polarizer subsystem, a transmitting and receiving subsystem, a servo drive digital display subsystem and a computer subsystem, wherein the antenna receiving turntable subsystem is respectively connected with the transmitting and receiving subsystem and the servo drive digital display subsystem, the transmitting polarizer subsystem is respectively connected with the transmitting and receiving subsystem and the servo drive digital display subsystem, and the computer subsystem is respectively connected with the transmitting and receiving subsystem and the servo drive digital display subsystem. The antenna receiving turntable subsystem comprises an azimuth turntable, a one-dimensional translation device which is arranged above the azimuth turntable, a support which is fixedly connected to the top of the one-dimensional translation device and an antenna polarizer which is installed on the top end of the support. With the adoption of the system, the automatic measurement and control of a fuze antenna can be realized, the long-time manual operation can be avoided, and the test efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the field of measurement technology, and in particular relates to a fuze antenna far-field automatic measurement system and a measurement method, which can be used to accurately and quickly test the direction characteristics of the main section of the fuze antenna. Background technique [0002] The radio proximity fuze is an important missile control device in the weapon system, and the fuze antenna is the "eye" of the radio proximity fuze, which is a branch of the aircraft antenna. In addition to the commonality of aircraft antennas, it also has some unique performance requirements. Fuze antenna design is the key to fuze product design, it will directly affect the acquisition of fuze signal. The early fuze antennas were mainly electric small antennas working in the P and L bands, and the most common ones were inductively loaded cap antennas and strip single-loop antennas. In recent years, due to the continuous improvement of...
