Problems solved by technology

At present, the domestic phased array antenna technology is mostly used in ground radars. The interface of the transmitting components on it is complex and the efficiency is low. The heat dissipation scheme mostly adopts complex systems such as air cooling or liquid cooling, which is not suitable for use on arrows.

Embodiment Construction

[0021] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] The design principles of the transmitting components are modularization, generalization, miniaturization, and complete functions to meet the selection needs of different types of phased array antennas in the S-band. The equipment on the arrow needs to provide the criterion of whether the product is working normally during the rocket flight. The launch component uses the detection voltage of the output power as the criterion for feedback and reporting.

[0023] like figure 1 As shown, a transmitting component circuit for an arrow-borne S-band phased array antenna provided by the present invention includes: a first serial-to-parallel conversion module, a second serial-to-parallel conversion module, a voltage stabilization module, a numerically controlled phase shifter, and a numerically controlled attenuation ampli...

Abstract

The invention provides a transmitting assembly circuit used for a rocket-mounted S-frequency-band phased-array antenna and a structure thereof. The structure comprises a circuit principle, a printed board, a cavity structure, a cover plate and an externally-connected socket. The circuit printed board adopts an epoxy copper-clad glass cloth laminated board. The cavity structure and the upper cover plate adopt hard aluminum material. The printed board is installed in the cavity structure. Externally-connected radio frequency input and low-frequency signal input sockets are directly welded on the printed board. The positions, which are corresponding to the two sockets, on the cover plate are provided with holes. A radio frequency output socket is installed on the cavity structure. Various technical problems that common transmitting assemblies are complicated in externally-connected port wire harness, high in power consumption, low in efficiency and numerous and jumbled in thermal design system are solved by the structure so that performance is excellent, quality is reliable, the phased-array antenna formed by the structure passes flight test evaluation, and thus the structure can be applied to multiple space carrier rockets of various model numbers.

Description

technical field [0001] The invention relates to a transmitting component circuit and structure for an rocket-borne S-band phased array antenna, which belongs to a launch vehicle space-based measurement, control and measurement system. Background technique [0002] The development of aerospace technology has put forward higher and higher requirements for launch vehicle measurement, measurement and control, communication and other technologies. Relying on traditional ground-based measurement and control technology can no longer meet the requirements of measurement and control coverage and real-time data transmission. The completion and use of my country's relay satellite system has provided a solid foundation for the launch vehicle to adopt space-based measurement and control technology, and has the conditions to realize full-flight measurement and control. [0003] The active phased array antenna has become an important part of the space-based measurement and control system o...
