<p>PURPOSE:To enhance the accuracy of a relative distance signal by distributing a sum signal after the extraction of a target signal without distributing the same until the target signal is extracted and controlling a guide flight body so as to obtain a relative speed signal and the relative distance signal. CONSTITUTION:After the first change-over control signal is inputted, a sum receiving signal is outputted to an one pair M distributors (23) by the first switch (hereinbelow referred to as SW1) and SW2 (22) outputs the sum receiving signal of the output of SW1 (21) to a relative speed detector (11) on the basis of the second change-over control signal of the output of an SW1,2 change-over signal generating part (20) until the second change-over control signal is inputted and, after the second change-over control signal is inputted, the sum receiving signal of the output of the one pair M distributer (23) is outputted to the relative speed detector (11). Since the sum receiving signal is not split into two ones before catching by the one pair M distributor and the S/W of the sum receiving signal supplied to the relative speed detector can not be deteriorated, the shortening of the extraction distance of a target signal is prevented.</p> |
