Embodiment Construction
[0015] The present invention is described in more detail below in conjunction with accompanying drawing example:
[0016] In conjunction with Fig. 1, tracking device of the present invention is made of antenna 1~5, servo platform 6, PIN attenuator 7~11, high amplifier 12~16, mixer 17~21, middle amplifier 22~26, local oscillator group 27, Digital receiver 28, wave detectors 29-33, summation circuit 34 and signal processor 35, antennas 1-5 are respectively connected to PIN attenuators 7-11, the PIN attenuators output to high-frequency amplifiers 12-16, local oscillator group 27 is controlled by the processor to generate a microwave signal with a fixed frequency difference from the incident signal frequency, which is input to the mixers 17-21 together with the output signal of the high-frequency amplifier to generate an intermediate frequency signal with a fixed center frequency. After the intermediate frequency signal is amplified by the intermediate frequency amplifiers 22-26, ...
