Embodiment Construction

[0022] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0023] The principle block diagram of the high-power vertical tile-type multi-channel digital transceiver sub-array described in the present invention is as follows image 3 As shown, the uplink baseband signal is phase-controlled by the FPGA, the system clock signal and the local oscillator signal LO to generate a transmission excitation signal through the SOC, and sent to the antenna radiation unit through the power amplifier, circulator and RF filter; the target received by the antenna is reflected back to the The wave signal is sent to the SOC with low noise through the radio frequency filter, circulator, and limiter, and the digital receiving signal is generated by down-conversion and other processing with the local oscillator signal LO inside the SOC.

[0024] The vertical tile-type integration method described in the present invention requires that the tra...

Abstract

The invention relates to a high-power vertical tile type multi-channel digital transceiving sub-array designing method, wherein a digital-numerical hybrid transceiving SOC is used for effectively reducing dimension, power consumption and cost of an active circuit. Modes of interlayer perpendicularity and no-cable interconnecting of a filter are used for settling a problem of vertical transmissionof a high-power microwave signal. Not only can high-efficiency of a microwave signal be ensured, but also tile dimension can be reduced. A circuit layout in a single radiation unit area is realized. Aform that the back of a power amplifier abuts against a heat radiator settles a heat radiation problem of a high-power heating element.

Description

technical field [0001] The invention relates to the technical field of radar, in particular to a high-power vertical tile-type multi-channel digital transceiver sub-array design method, which can be applied to the design field of two-dimensional active digital phased array radar transceiver components or transceiver sub-arrays. Background technique [0002] The key components in the two-dimensional active phased array radar are the transceiver components, and the number of array component units is huge. With the increasing performance of radar indicators, the requirements for the miniaturization and high integration of component units are becoming more and more stringent. Most of them are integrated in the form of transceiver sub-arrays. Its function is to realize the generation, phase shift and power amplification of the radar excitation signal; the low-noise amplification of the target reflection echo signal, down-conversion, and the digital signal after AD sampling is tra...
