Abstract :
The conventional positioning on artillery placement by means of seismic wave has poor accuracy. In this paper, a dual right square pyramid lattice model of passive acoustic positioning is proposed to resolve this problem. By means of Time Delay of Arrival (TDOA), a dual right square pyramid positioning geometric model is built. We studied under the constraint conditions by assuming that when dual right square pyramid arm length has length a, the base array spacing is 2b, the height of right square pyramid is c, and right square pyramid formation bottom height from ground is d. In this way, we further investigate the effects of these constraint conditions on positioning accuracy. Simulation results show that when a=1m, b=30m, c=1m, and d=1m, this dual right square pyramid model is better to the test. And the positioning error can be controlled within ± 0.35m in the testing area of 100m × 100m.
