<p>PURPOSE:To increase a target searching range at the time of catching a target, to improve target catching performance and to enhance shoot-down performance by adding a distribution switching unit, a signal switching unit, a signal process conversion correcting oscillator, a frequency mixer, a conversion signal switching unit, etc., to an airframe. CONSTITUTION:The airframe comprises a distribution switching unit 31 which distributes a sum signal received by an antenna 6 until a target 1 is caught, outputs sum signals A, B and outputs the sum signal to a distributor 7 after the target is caught, and a signal switching unit 32 which outputs the sum signal B until the target 1 is caught and outputs a difference signal of the output of the antenna 6 to an angle correlator 15 after the target is caught. Further, the airframe also comprises a frequency mixer 34 for generating a signal process conversion correction signal according to a signal process conversion signal from an oscillator 10 and a correction signal from an oscillator 33, wherein an output signal of the mixer 34 is output to an angle frequency converter 16 by a conversion signal switching unit 35 before the target 1 is caught, and an output signal of a signal process conversion oscillator 10 is output to the converter 16 after the target 1 is output to the etc., of a steering unit 20.</p> |
