The method to controll aotocorrelation intensity and related discrimination competence for a matched spacial filter by using two weights, EB (bias exposure) and f*(n) special frequency band), is discussed. Furthermore, application of this method is proposed for the synthesis of same-reference-beam noncoherent multiple matched spacial filters (SRNMF). Effects of the two weights on the autocorrelation intensity (IRt) and related disorimination competence (Cd) for the SRNMF are analyzed in detail. A formula is derived for estimating the optimized range of the exposure time (T). Experimental results are used to construct a curve of IRf vs. T, as well as curves for various fn(n) to show the relationships between and Ν and between Od and Ν· Where Ν is the overlay number of SRNMF.
