FM TARGET SIGNAL DETECTOR USING A CORRELATION ARRANGEMENT SUM FILTER AND A METHOD THEREOF CAPABLE OF REDUCING THE AMOUNT OF CALCULATION

摘要

PURPOSE: A FM target signal detector using a correlation arrangement sum filter and a method thereof are provided to obtain a correlation result of high precision according to a target Doppler shift frequency change, thereby rearranging and summing the obtained correlation result of the high precision.;CONSTITUTION: A correlation arrangement sum filter delays and rearranges each of a plurality of FM Doppler correlation results. The correlation arrangement sum filter sums the rearranged FM Doppler correlation results. The correlation arrangement sum filter finds a function of a correlation degree for a received target signal. A multiplier multiplies a result value of the correlation arrangement sum filter and a predetermined scale value. A comparator compares the result value of the multiplier and a detection standard value of a target. The comparator determines a location and whether or not of existing of the target.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Target detector; (BB) s'(n) rearrangement sum filter correlator; (CC) Comparator; (DD) Target detection and position information; (EE) Relation degree
