1. A control device comprising:
a control unit that performs control for estimating a positional relationship between a communication device having four or more antennas and another communication device on the basis of signals transmitted and received between the communication device and the other communication device, wherein
the control unit applies a weight parameter based on a reliability parameter that is an index indicating a degree of whether or not a signal is appropriate as a processing target for estimating a positional relationship between the communication device and the other communication device calculated on the basis of a signal received from the other communication device by the communication device to a phase difference between adjacent antennas of the four or more antennas of the communication device, and performs control for estimating the positional relationship.
