However , the correlation signal obtained by the classical matched filter is associated with large correlation sidelobes , large correlation bandwidth , and low optical efficiency 克服了經典的匹配濾波相關存在大的相關旁瓣、很大的相關帶寬和低的光效率等缺點。
However , the correlation signal obtained by the classical joint transform correlator ( jtc ) is associated with large correlation sidelobes , large correlation bandwidth , and low optical efficiency 但經典的聯合變換相關存在大的相關旁瓣、很大的相關帶寬和低的光效率等。
