Abstract

The invention provides a radar seeker system. The system comprises a frequency synthesizer and a receiver, the frequency synthesizer provides a full-coherent emission excitation signal, an emission excitation coupling signal, a frequency conversion local oscillator signal and a frequency conversion local oscillator coupling signal for the whole machine. Waveform control and pulse modulation can becarried out on the transmitted signal according to an instruction sent by the whole machine; the frequency hopping of the frequency conversion local oscillator signal can be realized in a certain frequency range to achieve the final carrier frequency jump function; an X-band receiver is a down-conversion and intermediate-frequency amplification assembly comprising four channels and is used for down-converting four paths of X-band radio-frequency signals input by a microwave front end to intermediate frequency and carrying out intermediate-frequency amplification, and the amplification amountof an intermediate-frequency receiving system can be adjusted under the action of externally inputting an AGC control code. A high-isolation switch is provided so that a receiving link blocking function is realized.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a radar radio frequency integrated system. Background technique [0002] At present, the radar seeker refers to the radar device on the missile used for target detection, tracking and providing the target position and motion parameters to the missile control system, and guiding the missile to the target. According to the energy source of the radar seeker to obtain target information, it can be divided into active radar seeker, semi-active radar seeker, passive radar seeker and composite radar seeker. The active frequency synthesis receiving component is an active radar seeker with its own radiation source. Contents of the invention [0003] The purpose of this section is to outline some aspects of embodiments of the invention and briefly describe some preferred embodiments. Some simplifications or omissions may be made in this section, as well as in the abstrac...
