PROBLEM TO BE SOLVED: To provide a flying object comprising a small-sized and lightweight composite seeker.SOLUTION: An active sensor antenna 10 transmits a radio wave for seek towards a target, receives the reflection wave thereof, converts the reflection wave into a first RF receiving signal and outputs the first RF receiving signal. An active sensor transmitter 11 outputs a transmitting signal relating to the radio wave for seek to the active sensor antenna. In an active sensor receiver 12, the first RF receiving signal outputted from the active sensor antenna is converted into a shared intermediate frequency signal and outputted. A passive sensor antenna 15 receives a radio wave which is any radio wave other than the radio wave for seek and comes from the target, converts the received radio wave into a second RF receiving signal and outputs the second RF receiving signal. In a passive sensor receiver 16, the second RF receiving signal outputted from the passive sensor antenna is converted into a shared intermediate frequency signal and outputted. A shared IF band receiver receives the shared intermediate frequency signals from the active sensor receiver and the passive sensor receiver and extracts a signal of a signal processing band corresponding to a seek mode of the target. |
