发明名称 APPARATUS FOR DISCRIMINATING TARGET
摘要 PURPOSE:To enable the discrimination of a target within a short time, by preliminarily storing the space frequency of a target to be discriminated to compare the same with input frequency. CONSTITUTION:The signal outputted from a receiving part 11 is supplied to a conversion part 12. For example, the conversion part 12 is constituted of a plurality of filters different in center frequency and divides the outer signal of the receiving part 11 at every frequency component to detect space frequency. In this case, the center frequency of each filter is set at every integer times of the repeating frequency of the output of the receiving part 11 and the output of the conversion part 12 is supplied to a discrimination part 13 at every frequency component. The space frequency information of a target signal having being preliminarily obtained so as to correspond at every target is stored in a memory part 14 and introduced into the discrimination part 13 along with the output of the conversion part 12. The discrimination part 13 compares and collates the informations from the conversion part 12 and the memory part 14 and judges the coincidence degree of both of them to perform the discrimination of a target.
