Adaptive radar ratio method fixed clamp micro-nano microwave detecting and demodulating monolithic system

Abstract

An adaptive radar ratio method fixed clamp micro-nano microwave detecting and demodulating monolithic system of the invention is mainly composed of a six-port slot coupler, a microwave phase detectionmodule, a microwave frequency and power detection module and a demodulation module. The adaptive radar consists of an antenna, a transmitting-receiving conversion circuit, a ratio method fixed clampmicro-nano microwave detecting and demodulating monolithic system, a signal memory, a signal analyzer, a microwave signal reconstructor, a microwave signal modulator, and a microwave signal power amplifier. An indirect heating microwave power sensor uses polycrystalline silicon nanowire clusters to form a thermocouple arm. The polycrystalline silicon nanowire clusters have thermal conductivity much lower than that of a conventional bulk material, have high thermoelectric conversion efficiency, and can greatly improve the sensitivity of the microwave detection system. The above structure can integrate the power detection module, the frequency detection module, and the phase detection module of the microwave signal, and can simultaneously and synchronously detects the power, the frequency and the phase of the microwave signal and demodulates a modulated signal.

Description

technical field [0001] The invention proposes a micro-nano microwave detection and demodulation monolithic system for fixed-supported beams by ratio method in self-adaptive radar, which belongs to the technical field of micro-electro-mechanical systems. Background technique [0002] Once the enemy's radar signal is not obvious enough or is an unknown signal, the electronic countermeasure system of the existing radar cannot quickly and accurately identify the enemy's radar system, so that the countermeasure effect will be seriously reduced. The new advanced adaptive radar electronic countermeasures include two key systems: adaptive radar reconnaissance and high-fidelity deception. Adaptive radar reconnaissance is able to analyze the working status and performance of the radar system according to the structural characteristics of unknown radar signals. Select the best and most targeted confrontation pattern, and then adaptively adjust the confrontation pattern and parameters a...

Problems solved by technology

However, in the existing technology, the detection of the power, frequency and phase of the microwave signal is carried out by using large-scale devices such as counters, resulting in large volume, high power consumption, narrow frequency band, and low integration of the entire system. Disadvantages, in addition, for more complex microwave modulated signals, traditional communication technology needs to use another system for demodulation, which will also cause the above problems, and at the same time increase a lot of cost, making it difficult to use in adaptive radar
