A kind of RSSD(Received Signal Strength Difference) location method is proposed aiming at locating the uncooperative radiation source passively with high accuracy based on energy limited clustering sensor network. Two rounds cooperative location scheme relying on TDOA(Time Difference Of Arrival) location is proposed, in which RSSD is subsidiary and TDOA location is the main method. The preliminary estimation of target position is made by RSSD location method; then some clusters are selected with high expected accuracy to make further locating according to the CRB(Cramer-Rao Bound) of TDOA. Final estimation of target position is made by weighted averaging of these TDOA locating results. Simulation results show that, the proposed modified measures can improve the locating accuracy compared with clusters selection rule and locations fusion method based on GDOP(Geometry Dilution of Precision); and RSSD/TDOA cooperative location scheme can alleviate network loading effectively, extend network lifecycle, and achieve high accuracy of locating, therefore it has good application prospects in engineering practice.
