Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 0:
1. A method comprising:
developing a range between a transmitter of a transmitted signal and one of:
a first antenna of a receiver that received the transmitted signal; or
a second antenna of the receiver that received the transmitted signal;

developing a first phase value as a function of a complex baseband impulse response of the transmitted signal received at the first antenna;
developing a second phase value as a function of a complex baseband impulse response of the transmitted signal received at the second antenna;
developing a path difference value as a function of the first phase value and the second phase value; and
developing a location of the transmitter relative to the receiver as a function of the range, the path difference value, and a distance between the first antenna and the second antenna.
