NOISE ADAPTIVE SONAR SIGNAL PROCESSOR

Title:

NOISE ADAPTIVE SONAR SIGNAL PROCESSOR

Document Type and Number:

WIPO Patent Application WO2005006009

Kind Code:

A3

Abstract:

A sonar system (100) has a cross correlator (108) that processes both primary and secondary signals to detect cross corelation peak.The system includes a sensor (102), a transmitter (103), a receiver (104) a plurality of band-pass filters (106), a cross-correlator (108) and a data analyzer (110). The sonar system (100) estimates the range of a target (112) based on the detected cross correlation peak. A transmitter (103) changes the frequency of the primary signal based on the estimated or predetermined SNR (signal-to-noise ratio) in an environment.
