Description
Technical field
The utility model relates to the marine navigation radar system equipment, is specially the marine navigation radar transceiver device.
Background technology
Marine navigation radar is the radar that ensures ship's navigation, also claims marine radar.It is specially adapted to night, greasy weather guiding ship discrepancy bay, passes through ditch and cabotage, mainly plays the crashproof effect of navigation.
The equipment radar starts from during the World War II on the ship, expands civilian merchant ship after the war gradually to.International Maritime Organization (IMO) (IMO) regulation, the above ship of 1600 tonnages must the equipment navar.A vital task of navar is that target is marked and drawed, and this task changes by robot radar plotting device just gradually to be served as.International Maritime Organization (IMO) stipulates that also the above ship of all 10,000 tonnages progressively installs this device.
General radar is illustrated in the center of plane position indicator (PPI) (seeing radarscope) to self as fixed point.But in navigation, boats and ships are always done relative motion with fixed target or moving target from motion.The radar that adapts to maritime environment should be the radar of real motion, must be able to import the speed of a ship or plane and the course of boats and ships self automatically, and data must be quite accurate.
After the World War II, the basic structure of microwave marine radar does not have very big change, and the principle of work of magnetron transmitter, high sensitive receiver, diplexer, antenna and display is all with former identical, but Performance And Reliability is improved.Application solid-state electronic technology is greatly improved the reliability of equipment.The modern navigation radar is except that magnetron with the cathode-ray tube (CRT), and other active circuit elements all use transistor and integrated circuit basically.Because circuit improves, pulse width reduces to 0.1 microsecond from 1～2 microsecond, and the magnetron peak power is brought up to 50 kilowatts from 3 kilowatts, thereby target discrimination and sensitivity are improved.The leaky wave antenna array makes antenna beamwidth reduce to 0.7 ° or 0.8 ° from 2 °, and the target azimuth resolving ability is improved.Because these improvement can be depicted course line formula image on 40 centimetres of plane position indicator (PPI)s, be convenient to boats and ships and when along the coastline navigation and entering and leaving port, mark and draw.The later stage sixties; Utilize small-size computer to succeed in developing robot radar target following and estimating system; It can handle radar video voltage, and the detection and tracking target is measured the relative motion between boats and ships and the target; Motion and closest approach that scheduled target is following assist human pilot to take to avoid action.It is the visual plant in the navigation field that navar and robot radar are marked and drawed device, is the necessaries that makes a land, guides boats and ships discrepancy harbour and ditch.
Summary of the invention
The purpose of the utility model is to provide a kind of marine navigation radar transceiver device; Can realize that radar return information normally receives and launches; Make marine navigation radar ensure ship's navigation; Especially be specially adapted to night, greasy weather guiding ship discrepancy bay, pass through ditch and cabotage, play the crashproof effect of navigation.

The utility model marine navigation radar transceiver device; Can realize that radar return information normally receives and launches; Make marine navigation radar ensure ship's navigation, especially be specially adapted to night, greasy weather guiding ship discrepancy bay, pass through ditch and cabotage, play the crashproof effect of navigation.
Description of drawings
Fig. 1 is a marine navigation radar transceiver device theory structure synoptic diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the utility model transceiver device mainly comprises radiating portion, receiving unit, antenna part and terminal block and control panel 5, wherein:
Said radiating portion comprises magnetron 22, circulator 4 and the modulation panel 21 that can produce high-power ultrahigh frequency concussion; The output and the circulator of magnetron link; The input end of magnetron is connected with modulation panel; Vibrated by the control magnetron generation ultrahigh frequency of modulation panel, electromagnetic wave is propagated to antenna 11 along circulator; The modulation panel input end is connected with terminal block and control panel.
Said receiving unit comprise circulator 4, limiter 31 and in put plate 32; The linear in order non-closed serial connection of three; Put the plate output terminal in said and be connected with terminal block and control panel, signal successively through limiter with in put plate and handle after, finally by terminal block and control panel output.
Said antenna part comprises motor 12 and antenna 11, and the emission of radar electromagnetic wave and reception are shared said antennas, and motor output shaft is connected with the antenna input shaft, and motor driver is connected with terminal block and control panel respectively.
Said radiating portion, the most importantly magnetron that can produce high-power ultrahigh frequency concussion.The output and the circulator of magnetron link, and when it received the control generation ultrahigh frequency vibration of modulation panel, electromagnetic wave was just propagated to antenna along circulator, and gathers to become " wave beam " to launch to the direction of surveying by antenna.But electromagnetic emission should not be continuously, not so will successively obscure mutually from the echo of thing mark reflection and can't carry out the measurement of distance.
Therefore, the emission of radar transmit-receive machine (as transmitter time) is interrupted to be carried out, and the interval of twice emitting must long enough, just allows to do to launch for the second time after the echo that should be scheduled to maximum detectable range by the time arrives.This same interrupted working method with human pulse is called " pulsed modulation ".Wherein modulation panel control magnetron vibrates to produce powerful pulse according to predetermined cycle, width.
Because what magnetron produced is the ultrahigh frequency vibration, its frequency of echo that reflects from the thing mark is constant.For the echoed signal of high like this frequency, transceiver device (as receiver time) is the ability that do not have to amplify, and only way is to manage to make the frequency of echo to become intermediate frequency, and it just might be received machine and receive and amplify.Signal through limiter with in put plate and handle after, export by control panel.
Motor in the transceiver device mainly is used for adjusting the rotating speed of antenna, by terminal block and control panel control.
The emission of radar electromagnetic wave and reception are shared antennas.Therefore, one " Switching Power Supply " is installed in transceiver device.When magnetron was launched, Switching Power Supply coupled together the antenna of magnetron and radar.When transceiver was worked, receiving unit was in "on" position always, was supplied power by control panel.
