1 . A radar system comprising:

a first radar component and a second radar component, at least one of the first radar component and the second radar component configured to transmit at least one monitoring wave, and at least one of the first radar component and the second radar component configured to receive at least one reflected wave, the first radar component and the second radar component comprising an active mode and a passive mode, the active mode defined by the receiving of a power supply;

a processing unit configured to process at least one reflected wave signal received from at least one of the first radar component and the second radar component, the reflected wave signal indicative of the at least one reflected wave; and

a controller configured to control at least one of the first radar component and the second radar component, wherein the controller maintains the first radar component and the second radar component in the active mode during a first time period and a second time period.

2 . The radar system of claim 1 , wherein the passive mode is defined by at least one of:

the receiving of a reduced amount of the power supply and receiving of approximately none of the power supply.

3 . The radar system of claim 1 , further comprising a battery, the battery configured to transmit the power supply to at least one of the first radar component and the second radar component.

4 . The radar system of claim 1 , further comprising a panel, the panel configured to transmit the power supply to at least one of the first radar component and the second radar component.

5 . The radar system of claim 1 , wherein the controller maintains at least one of the first radar component and the second radar component in the active mode during a third time period.

6 . The radar system of claim 5 , wherein the at least monitoring wave is transmitted and the at least one reflected wave is received during the first time period, the second time period, and the third time period.

7 . The radar system of claim 6 , wherein the first time period, the second time period, and the third time period are each respectively less than 300 microseconds.

8 . The radar system of claim 5 , wherein at least one of the first radar component and the second radar component comprise a warm-up period, the controller configured to maintain at least one of the first radar component and the second radar component in the active mode during the warm-up period.

9 . The radar system of claim 5 , further comprising a first interval between the first time period and the second time period, and a second interval between the second time period and the third time period, the controller configured to switch at least one of the first radar component and the second radar component to the passive mode during at least a portion of at least one of the first interval and the second interval.

10 . The radar system of claim 9 , wherein the first interval is shorter than the second interval.

11 . The radar system of claim 9 , wherein the first interval is predefined and the second interval is variable.

12 . The radar system of claim 11 , wherein the processor is operably connected to the controller, the processor configured to increase or decrease the second interval.

13 . The radar system of claim 1 , wherein the radar system is configured to detect the presence or non-presence of a human within a building.

14 . A method for operating a radar system comprising a first radar component, a second radar component, a processing unit, and a controller, the first radar component and the second radar component comprising an active mode and a passive mode, the method comprising:

maintaining, with the controller, the first radar component and the second radar component in the active mode during a first time period and a second time period, the active mode defined by the receiving of a power supply; and

switching, with the controller, at least one of the first radar component and the second radar component to the passive mode during at least a portion of a first interval, the first interval defined between the first time period and the second time period.

15 . The method of claim 14 , wherein the controller maintains at least one of the first radar component and the second radar component in the active mode during a third time period.

16 . The method of claim 15 , further comprising switching, with the controller, at least one of the first radar component and the second radar component to the passive mode during at least a portion of a second interval, the second interval defined between the second time period and the third time period.

17 . The method of claim 14 , wherein the passive mode is defined by at least one of: the receiving of a reduced amount of the power supply and receiving of approximately none of the power supply.

18 . The method of claim 14 , wherein at least one of the first radar component and the second radar component comprise a warm-up period, the controller configured to maintain at least one of the first radar component and the second radar component in the active mode during the warm-up period.

19 . The method of claim 16 , wherein the first interval is predefined and the second interval is variable.

20 . The method of claim 19 , wherein the processor is operably connected to the controller to increase or decrease the second interval.
