Description
Technical field
The present invention relates to lunar orbital rendezvous docking microwave radar field, be specifically related to the multiplexing radar receiver of a kind of analog channel.
Background technology
Monopulse radar receiver, requirement to from antenna end, receive and, orientation, pitching three tunnel echoed signals carry out analogue signal amplitude normalization control, to meet rear end radar signal processor to inputting the requirement of three tunnel signal amplitude dynamic ranges and phase equalization.
The Monopulse radar receiver of prior art is three-channel monopulse radar receiver, adopt the separate analog channel in three tunnels to receive respectively and, orientation, pitching three tunnel echoed signals.The shortcoming of the Monopulse radar receiver of prior art is, due to the electronic devices and components of three paths, performance parameter is consistent completely, therefore, receiver three road signal output amplitude-phase consistencies are not ideal enough, and adopt receiver volume and the unit power consumption of three paths independent circuits designs all larger, complex circuit designs degree is higher, and cost is expensive.
Summary of the invention
The object of the present invention is to provide the multiplexing radar receiver of a kind of analog channel, can greatly improve amplitude and the phase equalization of radar receiver three-way output signal, and reduced power consumption and the cost of unit, dwindled the volume of unit.

Accompanying drawing explanation
The multiplexing radar receiver of analog channel of the present invention is provided by following embodiment and accompanying drawing.
Fig. 1 is the multiplexing radar receiver of the analog channel of the embodiment of the present invention.
Embodiment
Below with reference to Fig. 1, the multiplexing radar receiver of analog channel of the present invention is described in further detail.
Referring to Fig. 1, the multiplexing radar receiver of the analog channel of the present embodiment comprises the first tuner receiving unit 11, the second tuner receiving unit 12, third high a receiving unit 21, path selector switch 13, the first intermediate frequency amplifier 14 and the second intermediate frequency amplifier 22 frequently;
Described the first tuner receiving unit 11, the second tuner receiving unit 12 and third high frequently a receiving unit 21 receive respectively orientation, pitching He He tri-tunnel echoed signals;
Described the first tuner receiving unit 11 is connected with described path selector switch 13 respectively with the second tuner receiving unit 12;
Described path selector switch 13 is connected with outside radar signal processor (not showing in Fig. 1);
Described the first intermediate frequency amplifier 14 is connected with described path selector switch 13;
Described the second intermediate frequency amplifier 22 is connected with a described third high frequency receiving unit 21.
Antenna end by waveguide, send and, orientation, pitching three tunnel echoed signals, antenna end sends San road echoed signal and is high-frequency signal, described the first tuner receiving unit 11 receives high frequency orientation echoed signal, and by High frequency amplification, down coversion, filter action, high frequency orientation echoed signal is become to intermediate frequency orientation echoed signal, similarly, described the second tuner receiving unit 12 becomes intermediate frequency pitching echoed signal by high frequency pitching echoed signal, and a described third high frequently receiving unit 21 becomes intermediate frequency and echoed signal by high frequency and echoed signal; Intermediate frequency orientation echoed signal and intermediate frequency pitching echoed signal export described path selector switch 13 to, outside radar signal processor carries out corresponding switching according to path selector switch described in certain sequential control 13 according to specific needs, select output intermediate frequency orientation echoed signal or intermediate frequency pitching echoed signal, selecteed intermediate frequency orientation echoed signal or intermediate frequency pitching echoed signal are inputted described the first intermediate frequency amplifier 14; Intermediate frequency and echoed signal are inputted described the second intermediate frequency amplifier 22.
The multiplexing radar receiver of analog channel of the present embodiment adopts time-multiplexed mode, make two-way echoed signal (orientation echoed signal and pitching echoed signal) can share a poor path, thereby reached the object of channel multiplexing, under this design proposal, receiver only need to guarantee that intermediate frequency receiving cable two-way output signal is consistent and just can reach designing requirement, thereby reduced the complexity that circuit design and components and parts are selected.This scheme has been simplified the circuit design of receiver intermediate-frequency section, makes intermediate-frequency channel be reduced to two paths by original three paths, under the control of radar signal processor, and time-division processing orientation and pitching echoed signal as required.Because two paths of signals shares the communication of a-road-through road, thereby in the process that two paths of signals is processed at intermediate-frequency section, in circuit, the performance of components and parts is consistent, and design can be avoided because electric parameter between different components and parts cannot in full accordly cause two-way difference signal output amplitude and the bad defect of phase equalization like this.
The multiplexing radar receiver intermediate-frequency section of analog channel of the present embodiment only need to design two passes, making its circuit realize required electronic devices and components compares three path receivers and has reduced by nearly 1/3 quantity, and owing to having reduced by a path, when radar receiver designs, only need to consider only two paths output intermediate-freuqncy signal amplitude, the consistance of phase place, greatly reduce like this difficulty of design, make monopulse radar amplitude and phase equalization better, while is due to the minimizing of electron device in circuit, unit power consumption is corresponding reduction also, be convenient to Miniaturization Design.
