FPV Drone Threat Landscape
Thawj-Tus neeg-Saib (FPV) drones tau hloov pauv cov kev sib ntaus sib tua niaj hnub no, raug xa mus raws li qis- tus nqi siab tshaj - cov tub rog uas muaj peev xwm tawm tsam cov hom phiaj nrog qhov tseeb txaus ntshai. Tsis zoo li cov qauv UAVs uas tso siab rau GPS waypoints,FPV kamikaze dronesyog piloted nyob rau hauv tiag-lub sij hawm ntawm analog los yog digital video txuas, ua rau lawv tiv thaiv GPS-tsuas yog kev tiv thaiv thiab xav tau cov tswv yim tiv thaiv tshiab nkaus xwb.
Vim li cas FPV Drones nyuaj rau Counter
Ib txwm siv los tiv thaiv-drone systems tsim rau kev lag luam UAVs tawm tsam FPV kev hem thawj rau ntau qhov laj thawj:
- Tsis muaj GPS nyob ntawm:FPV drones ya ncaj qha los ntawm kev tsav dav hlau siv, ua rau GPS jamming tsis cuam tshuam.
- Kev kub ceev:Ib txwm FPV nres khiav tshaj 100 km / h, tawm hauv qhov rais qhov rais nqaim heev.
- Ntau zaus:FPV video txuas tuaj yeem ua haujlwm nyob qhov twg los ntawm 1.2GHz txog 5.8GHz, feem ntau hopping ntawm cov channel.
- Lub Sijhawm Ua Haujlwm luv luv:Los ntawm kev tshawb pom mus rau qhov cuam tshuam tuaj yeem nyob qis dua 10 vib nas this hauv ze- ntau yam xwm txheej.
Muaj txiaj ntsig Counter-FPV Jamming Techniques
A cov kws tshaj lij tiv thaiv-FPV drone jammeryuav tsum muaj kev cuam tshuam ob qho tib si video downlink thiab tswj uplink. Tus kws tsav dav hlau xav tau tiag tiag- lub sijhawm yees duab los coj lub drone mus rau nws lub hom phiaj - rhuav tshem qhov txuas no thiab qhov kev tawm tsam tsis ua tiav:
Video Link cuam tshuam
FPV video systems ua haujlwm ntawm 5.8GHz band (digital HD systems zoo li DJI O3 / O4) lossis 1.2GHz–2.4GHz rau kev teeb tsa analog. Dav davFPV video jammingthoob plaws 1.2GHz, 2.4GHz, thiab 5.8GHz ib txhij ua kom cov kev pab cuam tsis hais qhov twg zaus tus neeg tawm tsam siv.
Tswj Txuas Txuas Neutralization
Niaj hnub nimno FPV tswj kev cai (ELRS, Crossfire, DJI RC) kis thoob plaws 868MHz, 900MHz, thiab 2.4GHz bands nrog zaus-hopping kis spectrum (FHSS) tshuab. Tiv thaiv cov no yuav tsum taudav -spectrum tswj teeb liab jammingnrog lub zog txaus txaus kom dhau mus txawm tias zaus -agile receivers.
Multi-Layer FPV Defense Architecture
| Txheej Txheem | Technology | Kev sib koom ua ke | Kev ua tau zoo |
|---|---|---|---|
| Kev kuaj pom | RF spectrum analyzer + acoustic sensors | 500m – 2,000m | Ceeb toom ntxov |
| Mos-Tua (Jamming) | Multi-band anti-FPV jammer | 300m – 1,500m | Hlais video / tswj txuas |
| Hard-Tua | Kinetic interceptors / nets | 50m – 200m | Lub cev neutralization |
| Passive Defense | Anti-drone netting / tawb | 0m – 5m | Kawg -kev tiv thaiv kev nyab xeeb |
Cov lus pom zoo rau FPV Defense
Rau cov koom haum xav tauFPV drone tiv thaiv, Garpiya PRO thiab GW-series multi-band jammers muab cov kev pab cuam ib txhij -frequency coverage tseem ceeb rau kev cuam tshuam cov tshuab FPV niaj hnub no. Cov platforms no ua ke 433MHz txog 5.8GHz jamming hauv ib chav ua ke, nrog rau kev xaiv GPS L1 / L2 modules rau kev tiv thaiv dav dav -drone kev pab cuam tiv thaiv kev sib xyaw drone hem nrog rau ob hom kev tswj hwm thiab FPV.
