Research of TDOA/AOA hybrid algorithm under the NLOS environment

The hybrid algorithm of TDOA/AOA has better location accuracy than Chan algorithm under the CDMA network,but with the fall of AOA's accuracy,the location accuracy will drop gradually,and may below the Chan's.The article adds the amendatory factor in the traditional hybrid algorithm,through iteration gradually to mitigate the affect of Non Line Of Sight(NLOS) to the Time Difference Of Arrival(TDOA) measurement value,so we can get higher location accuracy.The simulation shows that the method here put forward can improve the location accuracy apparently,and the additional operation is rather small.
