Abstract :
This paper is concerned with assessing the impact of some MEMS technology on the accuracy of emitter location estimates based on frequency measurements made by a single platform. The main contribution of the paper is the derivation of an estimation error bound that quantifies the minimum accuracy improvement affordable by a particular sensor fusion scheme.
