Additions and Corrections to "SimplifiedSolution for a Class of Fading Memory Filters"'
Morgan's work on partially adaptive arrays [1] andthe summary of that given in [2], publications whichwere not known to the author, elaborate on the role of thecorrelation coefficient p of the auxiliary phasor vectorscharacterizing the performance of a partially adaptiveantenna, particularly in determining the output noisepower bound.
It is still worthwhile noting, however, and this wasemphasized in my paper considering the strong jammercase, that for pi < 1 the sign response of the mainantenna to the closely spaced jammers is of equalimportance to the system degradation as the correlationcoefficient. Even a further reduction of the jammerspacing, that is, an increase in IPI < 1, moving them intothe same sidelobe, may cause less resolution problemsthan a configuration where two closely spaced jammers,characterized by a correlation coefficient lower than theabove, are received in sidelobes of different signs. Thisin fact is a further consequence of the expression (21)derived in [1]. Morgan's interpretation of equation (9b) ofmy paper as a bound of noise enhancement is not correctsince, as it is stated clearly, equation (9b) applies onlywhen the sidelobe signs are different.
