technical field [0001] The invention provides a direct MEMS microwave detection and demodulation system for phase comparison method slot coupling in adaptive radar, which belongs to the technical field of micro-electromechanical systems. Background technique [0002] The electronic countermeasures of the new advanced adaptive radar include the two key systems of adaptive radar reconnaissance and high-fidelity deception, which actually detect and demodulate microwave communication signals. High-fidelity deception is to accurately store, copy, modulate and forward unknown enemy radar signals. This system must also be based on the detection and demodulation of microwave communication signals. It can be seen that microwave communication signal detection And demodulation plays a very important role in adaptive radar equipment. In the existing technology, large-scale devices such as counters are used to measure the power, frequency and phase detection of microwave signals. For co...

Problems solved by technology

In the existing technology, large-scale devices such as counters are used to measure the power, frequency and phase detection of microwave signals. For complex microwave modulated signals, traditional communication technology needs to use Another system, which will also cause problems such as large volume, high power consumption, narrow frequency band and low integration of the entire microwave measurement system, and also increase a lot of costs
