Abstract

The invention provides a millimeter wave processing device, which is used for processing an emission signal emitted to an object to be scanned and processing an echo signal reflected back from the object to be scanned, and comprises a millimeter wave local oscillation signal generation module, a transmitting module and a transmitting module. The millimeter wave local oscillator signal generation module comprises a millimeter wave frequency source used for generating a first millimeter wave local oscillator signal; and a time delay unit used for carrying out time delay processing on the first millimeter wave local oscillator signal generated by the millimeter wave frequency source so as to generate a second millimeter wave local oscillator signal. The transmitting module mixes a predetermined baseband signal with a first millimeter wave local oscillator signal generated by a millimeter wave frequency source so as to convert the predetermined baseband signal into the transmitting signalto be transmitted. And the transmitting module mixes the second millimeter wave local oscillator signal generated by the time delay unit with the echo signal received by the receiving module so as toconvert the echo signal into a to-be-processed intermediate frequency signal.

Description

technical field [0001] The invention relates to a millimeter wave processing device and a millimeter wave scanning system. Background technique [0002] With the development of radar technology, Synthetic Aperture Radar (SAR) has expanded from purely military applications to civilian applications, from outer space to the ground for long-distance detection and even close-range detection of human dangerous goods, from flat static two-dimensional Image reconstruction develops into stereoscopic three-dimensional dynamic imaging. Its development is inseparable from the progress of microwave transceiver channel technology. Especially from the current development of microwave transceiver channel, its working frequency band is getting higher and higher, its working frequency band is getting wider and wider, its integration level is getting higher and higher, and its electrical performance is getting better and better. Excellent, the cost is getting lower and lower. [0003] For th...
