Steerable antenna on platforms, fixed or mobile, are tracked to form an RF communication link by setting the width of the main lobe of the antenna beam pattern to be greater than the initial pointing uncertainty region and then concurrently scanning and progressively reducing the widths of the main lobes as the pointing uncertainty region is reduced to first acquire and then track the opposing antenna. The width of the main lobe is reduced such that the width of the main lobe is approximately fixed for each block. The antennas at opposite ends of the communication link may be scanned with scan patterns that are orthogonal to each other such that the demodulation of the received signal levels to signal direction of arrival at each platform is solely a function of the scan pattern of the receive antenna.
