Description
The utility model belongs to the checkout equipment of radiotelegraphy, especially for the checkout equipment of continuous wave dobla radar and fuse.
At present, be used for detecting the equipment of continuous wave dobla radar and fuse duty, the domestic product that Zhuzhou radio factory is arranged, the checker of the DR-582 radar of external more advanced TEMA company just like Denmark.This checker can detect radiofrequency signal, verification computational accuracy and simulating signal, volume is little in light weight, and is easy to use, quick, but a little less than this checker signal, be difficult to as the radar laydown target, can not observe simultaneously radar antenna directional diagram and can not be as the checkout equipment of 8mm fuse.
The utility model purpose, be to provide a kind of radar laydown target of doing to use, can observe the directional diagram of radar antenna again, the while can also be detected continuous wave dobla radar and the fuse checkout equipment that plays order intersection dobla frequency displacement that causes and the bullet order intersection process of simulating high-speed motion as the 8mm fuse.
The utility model is realized by following measures, this utility model is the checkout equipment that is used to check continuous wave dobla radar and fuse duty, it comprises crystal oscillator, frequency divider, detection amplitude modulator, switch, rate conversion switch and power supply, it is characterized in that it also includes antenna, lobe display, checks post, main frame chamber and microwave cavity.Reach outside surface in the microwave cavity and be provided with detection amplitude modulator, switch, antenna, inspection post, lobe display, rate conversion switch, power light and ground lug, be provided with crystal oscillator, frequency divider and power supply in the main frame chamber; Main frame chamber and microwave cavity connect firmly, and antenna links by switch and detection amplitude modulator, and wave detector and lobe display link, and amplitude modulator and rate conversion switch link, and connect frequency divider successively, crystal oscillator and power supply, check that post is in parallel with crystal oscillator.This utility model is a kind of simulator, and just a kind of passive type transponder as long as radar is aimed at simulator launched microwave signal, just has modulation signal and is modulated on the carrier wave and reflects as echoed signal.By two branch roads its principle of work is described respectively according to duty, now define wave detector, this road of lobe display is the I branch road, the definition amplitude modulator, rate conversion switch, frequency divider, crystal oscillator, inspection post and this road of power supply are the II branch road, its two kinds of duties are finished its function respectively by switch control I branch road and II branch road.When switch was transformed into the I branch road, it was f that the simulator antenna receives frequency
CMicrowave signal be added on the wave detector, be that a direct current electric current is added on the lobe display and shows after the detection, size by its indication, can judge the electromagnetic size of radar emission, the position of mobile simulator, but the also relative variation of the directional diagram of the instrumentation radar antenna of summary or space each point electromagnetic field size.When switch was transformed into the II branch road, the frequency that the simulator antenna receives radar emission was f
CElectromagnetic wave be added on the amplitude modulator, simultaneously produce the very high modulating frequency of a frequency stability also to be added on the amplitude modulator by crystal oscillator, produce a modulated wave.This modulated wave is made up of three frequency components, i.e. carrier wave f
C, upper side frequency f
c+ f
dWith lower side frequency f
c-f
dThis modulated wave is delivered to a day wire spoke width of cloth ejaculation through switch, received, after the detection of radar wave detector, just obtain the dobla frequency f of simulating by radar antenna
d, this signal to display, can demonstrate and f after amplification waits processing
dCorresponding speed.By the correctness of display speed, judge whether operate as normal of radar, also it can be checked the total system rate accuracy of radar as a calibration speed.Size by the radar receiver output amplitude simultaneously can be judged whether run-home of radar, equally also can judge whether radar has aimed at simulator by the size of simulator lobe display.
This utility model is compared with prior art, and following positive effect is arranged: (1) in the open air or during shooting range measurment, it can be used as run-home and uses, for X-band, as the about 26dB of tested dobla continuous wave radar antenna gain, during the about 100mW of emissive power, then measuring distance can reach about 150m.(2) be used for the bullet order intersection process that the 8mm fuse can be simulated high-speed motion.(3) realized easy, fast tested radar is detected, promptly do not need external AC and DC power supply, use easy and simple to handlely, set up conveniently, available hand is taken or is clipped on the tripod, as long as one press switch, the size that can check emissive power with have or not.Just can check whether operate as normal of radar system if press power switch.Except above-mentioned points, other characteristics see the following form.
| Instrument title function volume mm weight kg structure feature process-cycle cost handling characteristics signal V | This simulator detects radiofrequency signal, antenna radiation pattern is used for the radar laydown target, the verification computational accuracy, simulating signal Φ 80 * 320 0.26 (not containing battery) flashlight type (No. 1 battery of 3 joints) about 4 hours low (if selling 700 yuan/outward) is easy, be 4.4V apart from radar 3m test echo signal amplitude fast | 640 radar checker analog signals, verification computational accuracy about 140 * 200 * 320 about 5 wooden portable instrument boxes long higher (selling 1600 yuan/platform) set up inconvenience | DR-582 radar checker detects radiofrequency signal, the verification computational accuracy, simulating signal Φ 64 * 266 0.52(do not contain battery) metal and plastic casing form housing to form (No. 1 battery of 3 joints) long easy, apart from radar 3m test, echo signal amplitude is 0.2V fast |
Know that from last table this simulator is except above-mentioned characteristic, volume is little, in light weight, process-cycle is short, cost is low, save material and be its obvious advantage, only need buy the head processing of the electric torch of two three batteries and an electric torch because of its machine shell, its cycle is not more than 4 hours, need not electroplate coated simultaneously.This simulator parabola antenna is the lamp bowl that adopts electric torch, and to the about 14dB of its gain of X-band, the detection crystal is placed on its focus, thus do not need outsourcing antenna and wave detector, thus volume, weight, cost are reduced greatly.In addition because of adopting powered battery, the common metal that (added the skim plastic barrel in its battery case of the checker of DR-582 radar) except plastic construction is not handled as there being special coated, be perishable, do not guarantee quality, therefore through repeatedly scheme comparison, think that the technology of electric torch preventing battery corrosion is very ripe, be worth using, not only do not have problem to be processed, the battery case that reduces cost as this simulator of more ensuring the quality of products is an ideal structure.
