Abstract

The invention discloses a monopulse VICTS phased array antenna, which comprises a radiation layer, a parallel plate waveguide layer and a feed network layer arranged from top to bottom, wherein the feed network layer is used for accessing four paths of same TE mode wave signals and carrying out feed processing on the four paths of same TE mode wave signals; four paths of different TEM mode wave signals including a sum beam, a pitch difference beam, an azimuth difference wave velocity and a matched load are obtained and output to a parallel plate waveguide layer, the parallel plate waveguide layer is used for transmitting the four paths of different TEM mode wave signals input into the parallel plate waveguide layer to a radiation layer, and the radiation layer is used for radiating the four paths of different TEM mode wave signals input into the radiation layer to a free space. The antenna has the advantages that the measurement precision of the monopulse technology and the flexibility of the VICTS phased array antenna are effectively combined, beam scanning of the upper half space of the antenna can be rapidly and flexibly achieved at the same time, and meanwhile the tracking speed and the tracking precision are high.

Description

technical field [0001] The invention relates to a VICTS phased array antenna, in particular to a single-pulse VICTS phased array antenna. Background technique [0002] The CTS (Continuous Transverse Stub) array antenna was first proposed by Raytheon Corporation of the United States in the 1990s, and a large number of planar antennas have been developed. As a further evolution of the CTS antenna array, VICTS (Variable inclination continuous transverse stub) technology can realize a two-dimensional beam scanning array with low profile, low power consumption and strong mechanical robustness while inheriting the original high efficiency. [0003] The VICTS phased array antenna is mainly composed of an upper radiating CTS disk and a lower feeding network disk. The electric wave propagation between layers is conducted in the air medium, and the impedance loss is reduced to a minimum, so the radiation efficiency is greatly improved. The VICTS phased array antenna achieves two-dime...
