It is dynamic；Object is moved back and forth relative to the Doppler radar.
In one embodiment of the application, Doppler radar electromagnetic signals can be utilized, and receive anti-through object
Electromagnetic wave signal after penetrating.By frequency of the frequency relative to electromagnetic signals for calculating the electromagnetic wave signal after reflecting
Frequency displacement calculates direction and the speed of the action of object in conjunction with following formula：
Wherein, fdFor frequency displacement, the difference of the frequency of the frequency of the electromagnetic wave signal as reflected and the electromagnetic wave signal of transmitting；
V is object movement speed；λ is wavelength.Work as fdFor positive number when, indicate that object close to Doppler radar, works as fdFor negative when, table
Show object far from Doppler radar.Correspondingly, when v is positive number, object is indicated in close Doppler radar, when v is negative
When, indicate object far from Doppler radar.
Direction that can be by the action of the object detected and its variation, determine the type of action of object.
Preferably, movement velocity that can be with the object obtained by calculation relative to the Doppler radar judges
Whether calculated movement velocity is judging calculated movement velocity within the scope of pre-set velocity within the scope of pre-set velocity
In the case of, the action that will identify that is determined as effectively acting, and judges type of action further according to effective action and generates phase
The control signal answered.Wherein, pre-set velocity range can be set according to actual needs, such as pre-set velocity range can be set
It is set to 0.5~2km/h.
By above-mentioned according to speed of moving body, so judge action whether be effective action method, can to avoid because
Ammunition (excessive velocities) or object are parallel by (component velocity in radar normal direction is smaller, and radar normal direction is hung down
Directly in the direction of panel) situations such as caused erroneous judgement.
As the preferred embodiment of one embodiment of the application, the reflection that the Doppler radar receives can also be believed
