On Localization of a Non-Cooperative Target with Non-Coherent Binary Detectors

Localization of a non-cooperative target with binary detectors is considered. A general expression for the Fisher information for estimation of target location and power is developed. This general expression is then used to derive closed-form approximations for the Cramer-Rao bound for the case of non-coherent detectors. Simulations show that the approximations are quite consistent with the exact bounds. Localization of a non-cooperative target using a number of sensors is usually performed through measurement of Time Difference Of Arrival (TDOA), Direction Of Arrival (DOA) or Received Signal Strength (RSS).
