ABSTRACT:
A system and method is described for determining a distance to a desired target via correlating a pulse modulated signal with its corresponding reflected signal, while compensating for noise error in the reflected signal to allow for a more precise distance determination. The system and method determine a phase shift of an echoed signal in response to a transmitted signal incident onto an object to thereby determine a distance, wherein the system analyzes an overlap region between a second signal that is a reflection of a first signal incident on the object. The first signal is modulated by one or more pulses having a defined modulation frequency. Further details and features are described herein.
