Abstract

PURPOSE: To increase the detection accuracy, by classifying the pulse with the frequency classification circuit and the time interval (TOI) classification circuit, comparing the result with the identifying table setting the objective pulse in advance, and detecting the objective pulse as a single pulse train.
CONSTITUTION: The pulse signal received on the antenna 1 is input to the frequency classifying circuit 5 via the band pass filter 2 and repetitive period (PRI) filter 3 to be classified into a plurality of frequencies. The result of classification is given to the TOI classification circuit 6 for TOI classification. The result of classification is fed to the comparator 7. In this comparator 7, the result of classification is compared with the content of the identification table 8 where the frequency of objective pulse dangerous from missile and TOI are set, and if in agreement, the alarm is made from the comparator 9.
