Ultra-wide band soil/tire interaction radar
First Claim
1. A system for generating at least one of tire, ground, and tire/ground data for an pneumatic tire having a casing forming a hollow inner portion for containing a gas, the pneumatic tire in contact with a ground surface, the system comprising:
- a radar transmitter, located within the hollow inner portion of the pneumatic tire, for generating a radar signal towards a portion of the pneumatic tire in contact with the ground surface;
a radar receiver for receiving a reflected signal from at least one of an interface between the gas and the casing and an interface between the casing and the ground surface; and
means for analyzing the reflected signal to produce at least one of tire, ground, and tire/ground data.

Abstract
A radar system for vehicle tire testing and analysis may be mounted within the casing of a vehicle tire to measure the location of the inner casing of the tire (tire deformation) as well as the location of the tire/soil interface (tire footprint). The radar system of the present invention may also be used to determine soil characteristics by analyzing the reflected signals. The present invention may have particular use in testing tires for use with on- or off-road surfaces. However, the present invention may also be used to monitor tire deformation, traction, footprint, and soil characteristics.

11. A method of generating at least one of tire, ground, and tire/ground data for an pneumatic tire having a casing forming a hollow inner portion for containing a gas, the pneumatic tire in contact with a ground surface, the method comprising the steps of:
-
generating a radar signal, using a radar transmitter located within the hollow inner portion of the pneumatic tire, towards a portion of the pneumatic tire in contact with the ground surface, receiving a reflected signal in a radar receiver, from at least one of an interface between the gas and the casing and an interface between the casing and the ground surface, and analyzing the reflected signal to produce at least one of tire, ground, and tire/ground data. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
