Abstract:

This report is concerned with the problem of time constants in adaptive arrays. The report presents an improved form of adaptive array feedback loop, which has the property that its time constants are fixed. This property is an advantage over the well-known LMS loop, for which time constants depend on received signal power. Fixed time constants are of interest because they simplify dynamic range problems for adaptive arrays in communication and radar systems. Author
