1. A direction finding system, comprising:
- a transmitter configured to generate a single carrier;
a plurality of receivers, each of which has a receiving antenna;
a phase comparison section configured to compare phases of signals received by said receivers to determine a phase difference between the received signals; and
an information processing section configured to perform a computation process for direction finding based on the phase difference.
