Abstract

The invention relates to an adaptive-radar ratio method based cantilever micro-nano microwave detection and demodulation system-on-chip which mainly comprises a six-port cantilever coupler, a microwave frequency detection module, a microwave phase detection module and a microwave power detection and demodulation module. The adaptive radar consists of an antenna, a receiving and transmitting conversion circuit, an MEMS (micro-electromechanical systems) microwave detection and demodulation integral system-on-chip, a signal storage unit, a signal analyzer, a microwave signal reconstruction unit,a microwave signal modulator and a microwave signal power amplifier. As an indirect-heating microwave power sensor utilizes a polysilicon nanowire cluster to form a thermocouple arm, the thermal conductivity is lower than that of the conventional materials, high thermoelectric conversion efficiency is achieved, the flexibility of the microwave detection system can be improved greatly, simultaneously synchronous detection of power, frequency and phase of microwave signals and demodulation of modulated signals can be completed, and thus, the adaptive-radar ratio method based cantilever micro-nano microwave detection and demodulation system on chip is implemented.

technical field [0001] The invention proposes an adaptive radar ratio method cantilever beam micro-nano microwave detection and demodulation monolithic system, which belongs to the technical field of micro-nano electromechanical systems. Background technique [0002] Radar is an effective sensor, and the process of acquiring information is an interaction with the environment. However, in complex and changeable environments, it is difficult for traditional radars to obtain good performance, so adaptive radars are born. Adaptive radar can intelligently change the information processing method according to environmental conditions, and this technology puts forward high requirements for the detection of signal power phase frequency in microwave technology. However, in today's microwave technology engineering, the detection of microwave signals is measured by some large devices, which have a series of problems such as large volume, high power consumption, narrow frequency band, ...
