摘要：
A radio direction finder system incorporating relatively small antennas is provided with a signal processing arrangement for artificially synthesizing variably shaped high frequency direction finding antenna receptivity patterns useful in a first mode for searching for the general location of a broadcasting high frequency transmitter and in a second mode for precisely tracking such a transmitter for navigation purposes.
