A device for responding to movement in or around a vehicle. In one example, the device comprises a radio frequency (RF) transmission circuit, a radio frequency (RF) transmission circuit, and a controller that is electrically coupled to the RF transmission circuit and RF reception circuit. The controller times the generation of control signals to create detection envelopes. The controller also determines motion within the detection envelopes, and generates an output based on the detection envelope that motion was determined within.

1. A device for responding to movement in or around a vehicle, the device comprising: a radio frequency (RF) transmission circuit;an RF reception circuit;a controller that is electrically coupled to the RF transmission circuit and the RF reception circuit, the controller configured to time a generation of control signals to create a detection envelope;detect motion within the detection envelope, the detection envelope including an inner detection envelope and an outer detection envelope;generate an alarm indicator when motion is detected within the inner detection envelope; andgenerate a pre-alarm indicator when motion is detected within the outer detection envelope. 2. The device according to claim 1, wherein the controller is configured to track a time interval that motion has been detected within the outer detection envelope. 3. The device according to claim 2, wherein the controller compares the time interval that motion has been detected within the outer detection envelope to a predetermined time interval. 4. The device according to claim 3, wherein the controller is configured to generate a second pre-alarm indicator when the time interval that motion has been detected within the outer detection envelope exceeds the predetermined time interval. 5. The device according to claim 4, wherein the controller generates the second pre-alarm indicator by sending a signal to an alarm system of the vehicle requesting the alarm system to sound a beep or chirp. 6. The device according to claim 1, wherein the detection envelope also includes a non-detection envelope having a one foot radius from the device, wherein no motion is detected within the non-detection envelope. 7. The device according to claim 1, wherein the RF reception circuit has multiple path processing including a first path and a second path, wherein the first path detects motion in the inner detection envelope and the second path detects motion in the outer detection envelope. 8. The device of claim 1, wherein the pre-alarm indicator includes turning on an interior light of the vehicle. 9. The device of claim 1, wherein the alarm indicator includes sounding a horn or siren belonging to the vehicle. 10. The device of claim 1 wherein, the detection envelope is one of a plurality of possible shapes, including a hemisphere and a toroid. 11. A method for responding to movement in or around a vehicle, the method comprising: timing, with a controller, the generation of control signals to create a detection envelope;detecting, with the controller and based on a received RF signal, motion within the detection envelope, the detection envelope including an inner detection envelope and an outer detection envelope;generating, with the controller, an alarm indicator when motion is detected within the inner detection envelope; andgenerating, with the controller, a pre-alarm indicator when motion is detected within the outer detection envelope. 12. The method according to claim 11, wherein a time interval that motion has been detected within the outer detection envelope is tracked with the controller. 13. The method according to claim 12, wherein the controller compares the time interval that motion has been detected within the outer detection envelope to a predetermined time interval. 14. The method according to claim 11, wherein no motion within a one foot radius of a motion detector is determined by the controller. 15. The method of claim 11, wherein generating the pre-alarm indicator includes turning on an interior light of the vehicle. 16. The method of claim 11, wherein generating the alarm indicator includes sounding a horn or siren belonging to the vehicle. 17. The method of claim 11 wherein, the detection envelope is one of a plurality of possible shapes, including a hemisphere and a toroid. 18. A motion detector comprising: a radio frequency (RF) transmission circuit;an RF reception circuit;a controller that is electrically coupled to the RF transmission circuit and the RF reception circuit, the controller configured to control the RF transmission circuit to generate an RF signal, control the RF reception circuit to receive a reflected RF signal from a first object in a first predetermined time for reception after transmission of the RF signal;control the RF reception circuit to generate a Doppler signal indicative of a distance between the first object and the motion detector based on the reflected RF signal;activate an alarm indicator based, at least in part, on a magnitude of the Doppler signal indicative of the distance between the first object and the motion detector;control the RF reception circuit to receive a reflected RF signal from a second object in a second predetermined time for reception after transmission of the RF signal;control the RF reception circuit to generate a Doppler signal indicative of a distance between the second object and the motion detector based on the reflected RF signal;activate a pre-alarm indicator based, at least in part, on a magnitude of the Doppler signal indicative of the distance between the second object and the motion detector. 19. The controller of the motion detector of claim 18, the controller further configured to track a time interval that the magnitude of the Doppler signal indicative of the distance between the second object and the motion detector is greater than a second predetermined threshold. 20. The controller of the motion detector of claim 18, the controller configured to activate the alarm indicator when the magnitude of the Doppler signal indicative of the distance between the first object and the motion detector is greater than a first predetermined threshold. 21. The controller of the motion detector of claim 18, the controller configured to activate the pre-alarm indicator when the magnitude of the Doppler signal indicative of the distance between the second object and the motion detector is greater than a second predetermined threshold.
