<p>PURPOSE:To detect the position of a target looked from a flight body, by knowing which is received the code generated by the first code generator or that generated by the second code generator with respect to data showing which side among upper and lower sides a target is present on. CONSTITUTION:A switch 14 is driven by the output of a synchronizer 26 and, when the output thereof is a high level, the switch 14 is connected to a receiving antenna 4c and, when said output is a low level, the switch 14 is connected to a receiving antenna 4d. The output of a reversal device 27 becomes a reversed level of the high or low output level of the synchronizer 26. Herein, since a comparator 9d outputs a high level when a receiving system detects the code of the first code generator 21a, the AND of the output of the synchronizer 26 and that of the comparator 9a is taken. When there is output in an AND circuit 18a, it is shown that a target is present in a lower and right direction, that is, in the first quadrant. Similarly, when there are outputs in AND circuits 18b-18d, it is shown that the target is present in the second-fourth quadrants. By this method, ignition circuits 10a-10d are respectively operated by the output pulses of the circuits 18a-18d and the optimum pattern explodes a head.</p> |
