Abstract

Abstract

To overcome the large errors and complexity of measuring the wave velocity of landing point location algorithm in target range, a method based on poisoning algorithm without velocity measurement is proposed. Nine accelerate sensors constitute pozidriv shaped array, which also consists of 2 sets of five-element cross array. DOA algorithm is used to pre-estimate the wave velocity, then the wave velocity as the initial parameter is set into the equation to calculate the initial position. Lastly, as the parameters the initial position and the velocity are set into the Taylor iterative algorithm to get the final location result. Because wave velocity need not to be measurement, measurement error can be reduced, wave velocity and position value can be calculated by iteration algorithm, so this algorithm makes the landing point location more simple, more accurate. The simulation verifies that this method is measurable, and the iterative algorithm is convergent in the range of 1000 meters.
