Intelligent dual-mode radar system based on a terahertz frequency band and imaging method thereof

An intelligent dual-mode radar system based on a terahertz frequency band, comprising:

• a transmitting module, which is used to generate and emit electromagnetic wave signals in a terahertz frequency band and supports dynamic switching between a close-range high-resolution mode and a long-range low-power consumption mode;
• a receiving module, which is used to receive echo signals reflected by targets of the transmitting module, and complete low-noise amplification and mixing processing of signals;
• a frequency synthesizer, which is connected to the transmitting module and the receiving module, and used to generate adaptive sweep bandwidth and sweep time parameters according to target distance requirements, and preset at least two waveform modes;
• an adaptive signal processing unit, which is connected to the receiving module, and used to dynamically adjust filter parameters and gain according to target distance working modes, and output target imaging data;
• and
• a control module, which is connected to the receiving module, the frequency synthesizer and the adaptive signal processing unit, and used to realize parameter configuration and mode switching of dual-mode collaborative work.
