A methodology is proposed for target strength measurements by using UltraWide Band (UWB) signals. Using high stability clocks for synchronization of the transmitter and receiver? Accurate time-of-flight measurements can be made between transmitters and receivers via direct and reflected acoustic paths. Target strength is calculated by comparing the correlation of the signals received from the direct path and reflected paths, with reference signals. This technique enables target strength measurements in negative SNR environments. The implementation of this methodology is described.
