ABSTRACT:
Delay profile creation sections7and8create a delay profile for each of fixed directivity reception signals combined using a plurality of fixed weight patterns. A path search section11detects a delay profile in which the maximum peak has appeared. An initial value weight selection section12selects the fixed weight corresponding to the delay profile in which the maximum peak has appeared as an initial value weight. An adaptive array antenna reception control section13uses this initial value weight as the initial value of an optimization algorithm to calculate the optimal weight of the adaptive array antenna. Thus, it is possible to reduce the time required to calculate the optimal weight by means of the optimization algorithm.
