The signal output interface is DB-J9 holes output interface, positioned at the lower left of guidance panel.
The present invention is a kind of millimeter speed-measuring radar device, vibrates high-frequency local oscillation frequency fo=35.1GHz/ that chamber produces
The sending signal of 37.5GHz, by isolator, the forward path of Jing circulators, is radiated front tested to dielectric lens antenna
On moving target, meanwhile, the backward channel of the sub-fraction power Jing circulators of local frequency fo can leak into the conduct of frequency mixer end
The local oscillation signal of frequency mixer；When local frequency fo transmission signal runs into mobile target in front, one can be reflected immediately
Frequency is the signal of fo+fd, then Jing circulators forward path is entered to frequency mixer with its local frequency fo after being received by lens antenna
Row mixing, the difference frequency fd for obtaining is exactly Doppler signal；Simultaneously frequency mixer has and when wave detector function, by high-frequency emission noise electricity
Pressure detection supplies rear end radar self-inspection demand into direct current signal；Doppler signal Jing low-noise amplifiers after mixing, bandpass filtering
After the process such as device, comparator and shaping circuit, the AC signal that peak-to-peak value is unloaded 8V or so is obtained, finally by signal output
Interface delivers to computer speed sampling system, carries out Automated condtrol.
Beneficial effects of the present invention：
The technical scheme is that a kind of millimeter speed-measuring radar device, high with operating frequency, strong anti-interference performance, survey
Convenient advantage is changed in the stable accurate, small volume of speed, installation and debugging, is protected from weather influences, and can effectively reduce traffic accident
Occur, have broad application prospects.
