Problems solved by technology

[0003] 1. Only the independently designed fuze transceiver antennas are installed at two symmetrical positions on the antenna surface of the seeker, and the common-aperture design of the seeker / fuze antenna is not really realized.
[0004] 2. The follow-up of the seeker and the fuze antenna need to be controlled by the antenna servo control system of the seeker. The machining is difficult, the control system is complicated, and the measurement error is relatively large when tracking a highly maneuverable target.
[0005] 3. The seeker and fuze can work synchronously, and the problem of co-frequency interference needs to be considered, which increases the complexity of system control

Embodiment 1

[0028] Such as figure 2 As shown, the present invention:

[0029] ① Firstly, according to the requirements of technical indicators such as the working frequency band, working bandwidth, and beam scanning range of the phased array common-aperture antenna, the common-aperture antenna array element is selected to have a wide-band, high-gain type antenna;

[0030] ② According to the requirements of the transmission power index, select the transmission power of the antenna unit, and determine the number of antenna units for a certain project to be 960;

[0031] ③According to the requirements of the system for the antenna array of the common-aperture detection system, the circular aperture and the diameter shall not be greater than 220mm, and combined with the requirements of the beam scanning range, such as image 3 As shown, the antenna units are arranged in an equilateral triangle, and the entire common-aperture antenna adopts an integrated assembly method. The phased array see...

Abstract

The invention provides a phased array seeker antenna, which comprises more than 300 phased array antenna units with an even number, wherein the working state of each antenna unit comprises a seeker mode and a fuse mode; the antenna units simultaneously work in the seeker mode; one part of antenna units work as transmitting antennas, one part of antenna units work as receiving antennas and the other part of antenna units are closed and do not work in the fuse mode; the types of the antenna units are uniquely determined by antenna technology indicators in the seeker mode; the number of the antenna units is uniquely determined by transmitting power indicators in the seeker mode; and the distribution structure of the antenna units is uniquely determined by a common-calibre detection system structure. According to the phased array seeker antenna, the detection requirements of seeker and fuse two different working modes on a target are achieved through time sharing of a same planar phased array antenna; a common-calibre antenna design of the seeker / fuse is really achieved; the phased array antenna is flexible, controllable and fast in beam switching; and the expandability of a system is strengthened.

Description

technical field [0001] The invention relates to a phased array seeker antenna. Background technique [0002] In order to meet the needs of high-precision and high-mobility strike targets, the idea of ​​integrated design of seeker / fuze is gradually adopted in air defense missiles. At present, the antenna of the seeker in air defense missiles mainly adopts the mode of mechanical servo control. In the integrated design of the head / fuze antenna, the antennas of the seeker and the fuze adopt independent transceiver mode design, and the transceiver antenna of the fuze is installed on the flat crack antenna of the seeker, and the antenna of the fuze can follow the guide The antenna servo control system of the head follows. Such as figure 1 Shown is a prior art seeker antenna, apparently prior art: [0003] 1. Only the independently designed fuze transceiver antennas are installed at two symmetrical positions on the antenna surface of the seeker, and the common-aperture design of...
