Title:
PULSE RAIN DETECTING DEVICE AND METHOD THEREFOR
Document Type and Number:
Japanese Patent JP3676283
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To overcome a problem such that, when the pulse train from a signal source included in a received pulse train is short and fluctuation is included in its PRI, the peak level at the position of the PRI is reduced, noise increases, and consequently the pulse train is hardly detected.
SOLUTION: This device and method is configured to compute a moving sum Dk(t) of complex trigonometric function within a moving window [t-ντk, t+ντk], which moves with time, based on arrival times tm of receiving pulse which construct a pulse interval tm-tn detected by simple PRI filters 121 to 12k.
