RADAR SYSTEM FOR AUTOMOBILE TRACKING
A radar system comprises a first radar transmitter arranged to transmit a first signal that propagates perpendicular to a direction of travel of a first object and a second object. The radar system further comprises a first radar receiver arranged to receive the first signal. Additionally, the radar system comprises a second radar transmitter spaced apart from the first transmitter and arranged to transmit a second signal that propagates perpendicular to the direction of travel of the first object. The radar system comprises a second radar receiver arranged to receive the second signal. The radar system further comprises a processor arranged to detect a space between the first object and the second object.

a second radar transmitter spaced apart from the first radar transmitter and arranged to transmit a second signal;
a second radar receiver arranged to generate second data in response to receiving a second reflected signal; and
a processor arranged to detect a space between the first object and the second object based on the first data and the second data.
2 . The radar system of claim 1 , wherein the processor is arranged to use the first data to detect the space between the first object and the second object.
3 . The radar system of claim 1 , wherein the processor is arranged to use the second data to detect the space between the first object and the second object.
4 . The radar system of claim 1 , wherein the processor is arranged to detect an end of the first object and a beginning of the second object.
5 . The radar system of claim 1 , wherein the first object is a first vehicle and the second object is a second vehicle.
6 . The radar system of claim 1 , wherein the first radar transmitter and the first radar receiver are arranged to create a first radar detection zone and wherein the second radar transmitter and the second radar receiver are arranged to create a second radar detection zone, and wherein the first radar detection zone is spaced apart and separate from the second radar detection zone.

8 . The radar system of claim 6 , wherein the processor is arranged to determine a duration of time from when the first object enters the first radar detection zone to when the first object leaves the second radar detection zone.
9 . A vehicle tracking system comprising:
a first radar transceiver arranged to generate a first radar detection zone oriented perpendicular to a direction of travel of a series of vehicles; and
a second radar transceiver arranged to generate a second radar detection zone, wherein the second radar detection zone is separate from and spaced apart from the first radar detection zone.
10 . The vehicle tracking system of claim 9 , further comprising a processor arranged to detect a respective space between each vehicle in the series of vehicles while the series of vehicles pass through the first radar detection zone.
11 . The vehicle tracking system of claim 9 , further comprising a processor arranged to detect a respective space between each vehicle in the series of vehicles while the series of vehicles pass through the second radar detection zone.
12 . The vehicle tracking system of claim 9 , further comprising a processor arranged to detect a respective space between each vehicle in the series of vehicles.
