摘要
A high-speed, highly sensitive microwave detection system and method, which uses the nonbolometric detection mechanism in a high- temperature superconducting thin film detector. A microwave signal is received by a broadband spiral antenna. The signal is modulated and optionally amplified before being transmitted to the superconducting detector through an impedance matching circuit. The superconducting detector generates an output voltage which is preamplified and then measured using a lock-in amplifier. A computer then records the measured output voltage.
