Abstract
Systems, methods, and other embodiments described herein relate to estimating direction of a surface acoustic wave (SAW) using temperature measurements from multiple resonators. In one embodiment, a method includes measuring temperatures of multiple resonators that are excited by a SAW using a sensor. The method also includes searching an angle from a temperature ratio of the multiple resonators using the temperatures. The method also includes estimating a direction of the SAW using the angle.

A detection system comprising:
- a memory storing instructions that, when executed by a processor, cause the processor to:
- measure temperatures of multiple resonators that are excited by a surface acoustic wave (SAW) using a sensor;
- search an angle from a temperature ratio of the multiple resonators using the temperatures;
- and
- estimate a direction of the SAW using the angle.
