ABSTRACT:
A method for pinpointing the actual coordinate location of a passive location device for a simulated battlefield condition is described. A plurality of actuators transmit to a passive location device which includes the method for determining its coordinate location. The coordinate location of a desired impact point is transmitted to the location device. The determination method initializes a starting coordinate location as the impact point of a round of munition. The method then iteratively determines the gradient direction of the position and moves the position estimate in the direction of gradient. As the estimated position approaches the true position successively smaller steps are taken and additional coordinate directions introduced into the solution until the convergence solution is terminated with least rms error in the neighborhood of the true coordinate position of the passive location device.
