Brief description of the drawings
Below the mark in content and figure that in the utility model instructions, every width accompanying drawing is expressed is briefly described:
Fig. 1 is radar module test mounting mechanism;
Fig. 2 is Doppler frequency simulation mechanism;
Mark in above-mentioned figure is: 1, power supply; 2, control module; 3, radio frequency unit; 4, oscillograph; 5, gain amplifier; 6, radar module.
Embodiment
Radar module 6 simulating test devices comprise radar module test mounting mechanism and Doppler frequency simulation mechanism, and radar module test mounting mechanism is used for monitoring radar module 6, and Doppler frequency simulation mechanism is used for simulating mobile object.
Known referring to Fig. 1, radar module test mounting mechanism comprises detected radar module 6, connects the gain amplifier 5 of radar module 6I or the output of Q mouth, and the oscillograph 4 being connected with gain amplifier 5.
The control module 2 known referring to Fig. 2, Doppler frequency simulation mechanism comprises radio frequency unit 3, is connected with radio frequency unit 3, and the power supply 1 of powering for control module 2, wherein power supply 1 is direct supply.
When installation, need guarantee the just radio frequency unit 3 to Doppler frequency simulation mechanism of radar sensor antenna of radar module test mounting mechanism, and keep radar sensor antenna and 3 days line parallels of radio frequency unit.Radar sensor energising is started working and outwards sends microwave signal by antenna, the microwave signal of the radio frequency unit 3 receiving radar sensor emission of Doppler frequency simulation mechanism, and the microwave signal receiving is sent to control module 2, control module 2 control again radio frequency unit 3 simulate mobile object send microwave to radar module test mounting mechanism.Radar module 6 will mix this signal and self internal oscillator frequency signal and produce a low frequency signal, through delivery outlet I or the output of Q mouth of radar sensor.Finally, just can realize by specialized equipment the measurement of frequency, amplitude and i/q signal phase place/amplitude balance degree.
For improving detection efficiency, radar module can be tested on mounting mechanism and the equal fixing test table of Doppler frequency simulation mechanism, easy to use, wherein radar module test mounting mechanism is affixed by the first pedestal and test desk, and Doppler frequency simulation mechanism is fixed on the second pedestal, this second pedestal is arranged on also can be along chute activity in the straight line chute on test desk, can meet different measuring demand by spacing, in addition, between the second pedestal and chute, there is lockable mechanism, be convenient to regulate rear locking.
