摘要

In principle, broadband null-steering may be achieved by using variable-length delay lines. However, because of the complexity of its implementation, this approach is not often attempted in practice. Instead, complex weights are normally used. This paper adopts the well known principle that a broadband null may be effectively achieved by creating a null that is spread over a wide angular range. Two methods developed for practical real-time DSP-based phased arrays are examined and their relative merit and limitations discussed.
