Abstract
The invention discloses a method for testing a Doppler mobile surveillance radar module, and the method comprises the following steps of: firstly, electrifying the tested Doppler mobile surveillance radar module to ensure that the Doppler mobile surveillance radar module transmits and receives radar waves after being electrified; secondly, driving a moving object to reciprocate by use of a power motor; thirdly, measuring the Doppler frequency shift generated by the movement of the moving object by use of the tested Doppler mobile surveillance radar module, and outputting a frequency shift signal to a frequency mixer; and finally, reading the signal mixed by the frequency mixer and transforming the signal into an amplitude waveform by an external oscilloscope, and judging whether the performance of the tested Doppler mobile surveillance radar module accords with a design requirement or not through the amplitude waveform. By using the method, the time for testing whether each Doppler mobile surveillance radar module accords with a design standard or not can be greatly shortened; and besides, the method is simple and convenient in operation, so large-scale test work of radar modules can be realized to ensure that the radar modules can be produced in large scale and in batches.
Description
Technical field
The present invention relates to a kind of method of testing, specifically.The method of testing of mobile detection radar module.
Background technology
Doppler's mobile detection radar module is the radar module that is used to detect mobile object, mainly is the reception condition of relying on frequency spectrograph to come test module at present for the detection technique of this module, thus whether the moving of judgment object.The received signal method of testing of Doppler's mobile detection radar module does not also have the standard of moulding, uses frequency spectrograph to carry out the demand that the test process trouble can't be accomplished scale production and test.
Summary of the invention
Problem and shortage at above-mentioned prior art existence; the purpose of this invention is to provide a kind of Doppler's mobile detection radar module that can make and realize large-scale test job, thereby make the production of radar module realize the method for testing of a kind of Doppler's mobile detection radar module of extensiveization.
For achieving the above object, the technical solution used in the present invention is a kind of method of testing of Doppler's mobile detection radar module, may further comprise the steps:
(1) with tested Doppler's mobile detection radar module energising, its radar wave that begins to the mobile object transmitting radar waves and accept to fire back of energising back by mobile object;
(2) driving mobile object by power motor moves back and forth;
(3) radar wave that this moment, tested Doppler's mobile detection radar module basis fired back records mobile object and moves the Doppler shift that is produced, and this frequency shift signal is outputed to mixer device;
(4) signal through the mixer device mixing is read and is converted into the amplitude waveform by the oscillograph of outside, judges by this amplitude waveform whether the performance of tested Doppler's mobile detection radar module adheres to specification.
The present invention is by carrying out corresponding action to radar module to the mobile object in the microwave dark room, the object that the radar wave that radar module sends is moved reflects, pass through this method, whether the radar wave that can test out radar module emission and emission meets design requirement, thereby can judge whether this radar module is qualified
Beneficial effect: the present invention can shorten the time whether each Doppler's mobile detection radar module of test meets design standards greatly, and it is easy and simple to handle, thereby can realize large-scale radar module test job, make the radar module can large-scale mass production.

Fig. 1 is the connection diagram of proving installation of the present invention.
Embodiment
Below in conjunction with specific embodiment, further illustrate the present invention, present embodiment is being to implement under the prerequisite with the technical solution of the present invention, should understand these embodiment and only be used to the present invention is described and be not used in and limit the scope of the invention.
As shown in Figure 1, the method for testing of Doppler's mobile detection radar module may further comprise the steps: at first with tested Doppler's mobile detection radar module energising, and energising back its emission and receiving radar ripple; Driving mobile object by power motor then makes it begin to move back and forth; The radar wave of tested Doppler's mobile detection radar module emission this moment is moved object and fires back again by this radar module reception, this radar module records mobile object by information processing and moves the Doppler shift that is produced, and this frequency shift signal is outputed to mixer device; Be input to by the oscillograph of outside after this frequency shift signal process mixer device mixing, oscillograph reads it and be converted into the amplitude waveform, just can judge by this amplitude waveform whether the performance of tested Doppler's mobile detection radar module adheres to specification.
