Multi-direction multi-range gate microwave intrusion detection device and method thereof

A microwave intrusion detecting device with a multi-direction and multi-range fence, comprising:

• a first detecting unit utilized to detect a first area and generate a first detecting result, wherein the first area comprises a first segment and a second segment, the first detecting unit comprises:
• a first emitting end utilized to emitting first microwaves;
• and
• a first receiving end utilized to receive reflected first microwaves;
• wherein the first detecting unit obtains the first detecting result according to the reflected first microwaves, the first detecting result comprises energy of the reflected first microwaves and a reflected distance of the reflected first microwaves;
• a second detecting unit utilized to detect a second area and generate a second detecting result, wherein the second area comprises a third segment and a fourth segment, and the second detecting unit comprises:
• a second emitting end utilized to emit second microwaves;
• and
• a second receiving end utilized to receive reflected second microwaves;
• wherein the second detecting unit generates the second detecting result according to the reflected second microwaves, the second detecting result comprises an energy of the reflected second microwaves and a reflected distance of the reflected second microwaves;
• a processor utilized to receive the first detecting result and the second detecting result and set a first threshold, a second threshold, a third threshold, and a fourth threshold corresponding to the first segment, the second segment, the third segment, and the fourth segment, respectively;
• and
• an alarm unit utilized to generate a warning message if the reflected distance of the reflected first microwaves falls in the first segment and the energy of the reflected first microwaves exceeds the first threshold, or if the reflected distance of the reflected first microwaves falls in the second segment and the energy of the reflected first microwaves exceed the second threshold, or if the reflected distance of the reflected second microwaves falls in the third segment and the energy of the reflected second microwaves exceed the third threshold, or if the reflected distance of the reflected second microwaves falls in the fourth segment and the energy of the reflected second microwaves exceed the fourth threshold;
• wherein the warning message comprises a location of the first segment, the second segment, the third segment, or the fourth segment.
