Embodiment Construction

[0032] Specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0033] The invention discloses a conformal phased array radar structure. The conformal phased array radar structure is arranged at the front end of the equipment requiring guidance.

[0034] Such as figure 1 As shown, the conformal phased array radar structure includes a conformal support 1, which adopts a hollow cylindrical structure with openings at both ends and a cavity inside. The side wall of the conformal support 1 is surrounded by several strip-shaped openings, the axial direction of the strip-shaped openings is parallel to the axial direction of the conformal support 1, and an antenna assembly 4 is embedded in each strip-shaped opening. 4 are arranged parallel to each other, and the axial direction of each antenna assembly 4 is parallel to the axial direction of the conformal support 1 . Several transceiver (T / R, Transmitter and Recei...

Abstract

The invention discloses a conformal phased array radar structure. The conformal phased array radar structure comprises a conformal support, a power supply module connected with one end of the conformal support and provided with a groove in one end which faces the conformal support, a wave controller fixed in the groove of the power supply module, which faces the conformal support, antenna modules installed on a housing of the conformal support in distribution mode, transmitting and receiving modules installed on the inner side wall of the housing of the conformal support in distribution mode and connected with the antenna modules through electric circuits, a power division network arranged in the conformal support and connected with the transmitting and receiving modules through electric circuits, a sum and difference network fixedly connected in the conformal support and a high frequency module fixedly connected in the conformal support. According to the conformal phased array radar structure, a conformal circumferential antenna array surface is formed by installing multiple groups of the antenna modules on the outer circle of the conformal support, and the function of searching a target in a body circumference area is provided to a device which needs guidance through continuous transmitting and receiving of antenna array surface wave beams.

Description

technical field [0001] The invention relates to a radar structure in the field of precision guidance, in particular to a conformal phased array radar structure. Background technique [0002] In the prior art, the radar seeker is usually installed at the front end of the equipment to be guided, and is used to search and track targets in front of the equipment to be guided and within a certain area in front of it, but for the circumferential direction of the equipment to be guided, it is to search blind spot. [0003] However, in some cases, the equipment to be guided is launched vertically. During the lift-off process, the seeker needs to perform a circular search on an area at a certain distance from the body. When the target is found, the equipment to be guided turns to point to the target. The front-end radar of the equipment to be guided searches and tracks the target. Therefore, there is a need for a seeker that not only has a search function for the front of the equip...
