本文通過分析認為,當信號集中的任一信號可表示為一系列已知信號的線性代數和時,信號集便構成可分解信號集,已知信號稱為基波信號;對可分解信號而言,基波系數構成一序列,當對指定的基波信號集分解唯一確定時,系數序列本身便是信號的一個表示;可分解信號采樣定理指出當基波樣值矩陣的秩等於基波數時,則由采樣點處的采樣樣構成的樣值序列必與基波系數序列一一對應,從而由該樣值序列構成的采樣必為完全采樣;可分解信號采樣定理中的推論指出,對信號集進行采樣,采樣頻率必須大於其信號分解的基波數與其對應時長之比;對有限帶寬信號,若基波信號為正弦信號時,由可分解信號采樣定理推論給出的結論與經典采樣定理一致。Secondly, this paper illustrated the nonlinear phase dynamic theory of the aia array and the application of it to power - combining and beam - scaning technique. according to these theories, the coupling parameter of nearest neighbors was found by experiment, then the two - element and three - element aia array were designed, and the result of measurement was in agree with that of the nonlinear phase dynamic theory, and the beam - scaning of two - element array was realized by tuning the free oscillation frequency of the elements
