    Abstract: An adaptive beam steering control system suitable for multiple element systems is provided for coherently forming a beam and tracking a dynamic scenario of a rapidly fading environment. The adaptive beam steering control system and associated method advantageously provide improved continuous beam steering with a faster response time and higher precision than normally attainable by using the greater slope of the nulling error function to perform the beam steering function. Although reciprocity of nulling and beam steering is normally only true for a single pair of elements, the method of the invention extends the process to larger arrays of elements.

    Abstract: An adaptive time delay control system is provided for matching the propagation time delay between two samples of a signal traveling through two independent paths so that they can be coherently combined for additional signal processing functions such as cosite interference cancellers, adaptive interference cancellers and adaptive beam formers. The adaptive time delay control system and associated method advantageously provide improved continuous matching of the two channels over a wider adjustment range while preserving both convergence speed over the full range and minimum jitter upon convergence by using composite autocorrelation functions to control (adjusting) a matching time delay in one channel.
