Systems and methods for intrusion detection using GHz beams
The present disclosure is directed to systems and methods that use 1 GHz to 1000 GHz sources and sensors to create an intrusion detection array that does not have the physical limitations of an Active IR sensor. The array is created by a plurality of wave sources and sensor pairs that form a plane of wave break beams. The plane detects an intruder as he/she passes through the beams.
1. A intruder detection system, comprising
a plurality of transmitter/receiver modules that create a beam grid formed of a plurality of beams having a frequency between 1 GHz and 1000 GHz;
wherein the plurality of beams have a beam divergence between 0.01 and 5 degrees;
wherein the transmitter/receiver modules comprises a transmitter and a receiver placed at a distance from the transmitter; and
wherein the transmitter comprises two or more beam generators that generate beams of different frequencies.
2. The intruder detection system of claim 1 , wherein the beam divergence is between 0.2 and 1.0 degrees.
3. The intruder detection system of claim 1 , wherein the plurality of transmitter/receiver modules are modular.
4. The intruder detection system of claim 1 , further comprising:
an alarm system connected to the plurality of transmitter/receiver modules.
5. The intruder detection system of claim 1 , wherein the receiver includes electronics that distinguish two or more simultaneously received beams of different frequencies.
6. The intruder detection system of claim 4 , wherein the alarm system is capable of determining the direction of intrusion.
7. An intruder detection method, comprising:
forming a beam grid comprising a plurality of beams having different frequency between 1 GHz and 1000 GHz by simultaneously generating two or more beams of the plurality of beams having different frequencies; and
simultaneously receiving, distinguishing and monitoring the plurality of beams for a break in one or more beams.
8. The method of claim 7 , further comprising;
initiating an alarm upon a detection of a break in one or more of the beams.
9. The method of claim 7 , further comprising:
determining the direction of intrusion by comparing the sequence of break in two or more beams.
10. An intruder detection system, comprising
a plurality of transmitter/receiver modules that create a beam grid formed of a plurality of beams having a frequency between 1 GHz and 1000 GHz;
wherein the plurality of beams have a beam divergence between 0.01 and 5 degrees;
wherein the transmitter/receiver modules comprises a transmitter and a receiver placed at a distance from the transmitter; and
wherein the receiver includes electronics that distinguish two or more simultaneously received beams of different frequencies.
11. The intruder detection system of claim 10 , wherein the beam divergence is between 0.2 and 1.0 degrees.
12. The intruder detection system of claim 10 , wherein the plurality of transmitter/receiver modules are modular.
13. The intruder detection system of claim 10 , further comprising:
an alarm system connected to the plurality of transmitter/receiver modules.
14. The intruder detection system of claim 13 , wherein the alarm system is capable of determining the direction of intrusion.
