摘要： PROBLEM TO BE SOLVED: To reduce an error in an estimated value of a state quantity of a target object to be produced by an error in the position of each wave receiving sensor.
SOLUTION: A state quantity concerning the target object is estimated by receiving a signal radiated from the target object, with three or more wave receiving sensors separated spatially and attached to an observing object which moves relatively with respect to the target object, obtaining an observation-time-difference time series being results of measurements of signal arrival time differences among the individual wave receiving sensors, and executing predetermined operation with respect to the observation-time-difference time series. Based on the observation-time-difference time series, a sensor-position-containing evaluation function which contains even the positions of the wave receiving sensors as objects of evaluation, along with the position and speed of the target object, is formed. A position and speed of the target object and positions of the wave receiving sensors which minimize this evaluation function are searched, and estimated values of these parameters are obtained. Moreover by using the estimated values of the positions of the wave receiving sensors, the positions of the wave receiving sensors to be applied to the formation of the evaluation function are corrected.
