Abstract:
1. An object detection and tracking support system that supports detection of an object using detection waves generated from a transmitter, comprising: a setting unit configured to store transmission level information set at said transmitter, object information of said object, and positional information of said transmitter and a receiver, the setting unit additionally configured to store one or a plurality of anticipated propagation loss values specified by a user; a transmission level obtaining unit configured to obtain transmission level information stored in said setting unit; a propagation loss function estimating unit configured to, based on positional information of said transmitter and said receiver stored in said setting unit, calculate the propagation loss as a propagation loss function expressed as a function of the distance and the direction viewed from said receiver; a target strength obtaining unit configured to, in regard to an object of object information stored in said setting unit, extract a target strength of the object from an external database; a propagation loss region estimating unit configured to, from the propagation loss function obtained by said propagation loss function estimating unit and the propagation loss value stored in said setting unit, calculate a direction and distance at which the propagation loss value is constant as a propagation loss region; a signal level region estimating unit configured to, based on the propagation loss region calculated by said propagation loss region estimating unit, the transmission level information obtained by said transmission level obtaining unit, and the target strength extracted by said target strength obtaining unit, calculate a region where the signal level from the object is constant as a signal level region, and makes an external display unit display the signal level region; and a detection signal level function estimating unit configured to, based on the transmission level information obtained by said transmission level obtaining unit, the propagation loss function calculated by said propagation loss estimating unit, and the target strength extracted by said target strength obtaining unit, determine a detection signal level function that expresses the signal level as a function of the distance and the direction from said receiver, and makes the external display unit display the detection signal level function used to assess detectability of the object, wherein said propagation loss region estimating unit expresses the propagation loss region as the solution to an N-degree polynomial equation of the distance from said receiver to the object.
