Antenna Anti-Jamming Technology and the Application of Passive Microwave Components

ʻO ka ʻenehana anti-jamming antenna e pili ana i kahi ʻano o nā ʻenehana i hoʻolālā ʻia e kāohi a hoʻopau paha i ka hopena o waho electromagnetic interference (EMI) i ka hoʻouna ʻana i nā hōʻailona antenna a me ka hoʻokipa, e hōʻoia ana i ka kūpaʻa a me ka hilinaʻi o nā ʻōnaehana kamaʻilio‌. ʻO nā loina koʻikoʻi ka hoʻoili ʻana i ka frequency-domain (eg, frequency hopping, spread spectrum), spatial processing (eg, beamforming), a me ka circuit design optimization (eg, impedance matching). Aia ma lalo kahi kikoʻī kikoʻī a me ka hoʻohana ʻana i kēia mau ʻenehana.

?I. Antenna Anti-Jamming Technologies?

?1. Nā ʻenehana Anti-Jamming Frequency-Domain?

?Hopu pinepine (FHSS):‌ Hoʻololi wikiwiki i nā alapine hana (e laʻa, he mau kaukani manawa i kēlā me kēia kekona) e pale aku i nā kaula hoʻopilikia, hoʻohana mau ʻia i nā kamaʻilio pūʻali koa a me nā ʻōnaehana GPS‌.

?Hoʻolaha Spectrum (DSSS/FHSS):‌ Hoʻonui i ka bandwidth hōʻailona me ka hoʻohana ʻana i nā code pseudo-random, e hōʻemi ana i ka mana spectral density a me ka hoʻomaikaʻi ʻana i ka hoʻomanawanui.

?2. Nā ʻenehana Anti-Jamming Spatial?

?Nā Antenna Naauao (Adaptive Beamforming):‌ Hoʻopuka i nā mea ʻole i nā kuhikuhi hoʻopilikia ʻoiai e hoʻonui ana i ka hoʻokipa hōʻailona makemake‌45. No ka laʻana, hoʻomaikaʻi nā antenna GPS anti-jamming i ke kūpaʻa kūlana ma o ka loaʻa pinepine ʻana a me ka beamforming‌.

?Kānana Polarization:‌ Kāohi i ka hoʻopilikia ʻana ma o ka hoʻohana ʻana i nā ʻokoʻa polarization, hoʻohana nui ʻia i nā kamaʻilio radar a me nā satellite‌.

?3.Nā ʻenehana anti-jamming pae kaapuni?

?Hoʻolālā Haʻahaʻa-Impedance:‌ Hoʻohana i ka impedance kokoke-zero-ohm e hana i nā kahawai ultra-narrow, kānana ʻana i ka hoʻopili uila waho.

?Nā ʻāpana Anti-Jamming (e laʻa, Radisol):‌ Kāohi i ka hoʻopili ʻana ma waena o nā antenna kokoke loa, e hoʻomaikaʻi ana i ka pono radiation.

?II. Nā noi o nā ʻāpana Microwave Passive?

ʻO nā ʻāpana microwave passive (e hana ana ma ka laulā 4-86 GHz) he hana koʻikoʻi i nā ʻōnaehana anti-jamming antenna, me:

?Nā mea hoʻokaʻawale & Circulators?

Kāohi nā mea hoʻokaʻawale i ka noʻonoʻo ʻana i ka ikehu RF, pale i nā transmitters; Hiki i nā circulators ke kuhikuhi i ka hōʻailona, ​​hoʻohana maʻamau i nā ʻōnaehana antenna transceiver.

?Nā ʻāpana kānana?

Hoʻopau nā kānana bandpass/bandstop i ka hoʻopilikia ʻana i waho, e like me ke kānana akamai i nā antenna GPS anti-jamming‌3.

?III. Nā hiʻohiʻona noi maʻamau?

?Nā noi koa:Hoʻohui ʻia nā radar missile-borne i ka hopping pinepine, ka hana polarization, a me nā ʻenehana MIMO e pale aku i ka hoʻopili paʻakikī.

?Kūkākūkā Kivila:Hiki i nā ʻāpana passive microwave/milimeter-wave ke hoʻouna i nā hōʻailona kiʻekiʻe ma nā ʻōnaehana 5G/6G.

ʻO Concept Microwave kahi mea hoʻolako honua i nā kānana maʻamauma na noi o kaʻO nā kaʻa lewa ʻole (UAV) a me nā ʻōnaehana counter-UAV, me ka kānana haʻahaʻa, kānana kiʻekiʻe, kānana notch/band stop, kānana bandpass a me nā panakō kānana.
