Q-bhendi uye EHF (Yakanyanya High Frequency) bhendi akakosha frequency mabhendi mumagetsi emagetsi spectrum, ane akasarudzika maitiro uye yakafara maapplication.
Q-bhendi:
Q-bhendi rinowanzo reva frequency renji pakati pe33 ne50 GHz, iri muEHF renji.
Zvikuru zvayo zvinosanganisira:
High frequency: pfupi wavelength, anenge 6 kusvika 9 mm.
Yakakwira bandwidth: yakakodzera kumhanyisa-kumhanyisa data kutapurirana.
Nzvimbo huru dzekushandisa dzeQ-band ndeidzi:
Satellite kutaurirana: inoshandiswa uplink uye downlink yeakakwira-throughput satellite (HTS) masisitimu ekupa Broadband Internet masevhisi.
Ground microwave kutaurirana: inoshandiswa kune ipfupi-kure, yakakwirira-inogonesa data kutapurirana.
Radio astronomy: inoshandiswa kuona yakakwirira-frequency radio masosi muchadenga.
Automotive radar: pfupi-renji radar inoshandiswa mune yepamusoro mutyairi rubatsiro masisitimu (ADAS).
EHF bhendi:
EHF bhendi inoreva frequency renji iri pakati pe30 ne300 GHz uye wavelength iri 1 kusvika 10 mm, saka inonziwo millimeter wave bhendi.
Zvikuru zvayo zvinosanganisira:
Ultra-yakakwirira frequency: inokwanisa kupa yakanyanya kukwira data kutapurirana mitengo.
Narrow beam: idiki antenna saizi uye yakasimba yakanangana.
Nzvimbo huru dzekushandisa dzeEHF bhendi ndeidzi:
Kukurukurirana kwechiuto: kunoshandiswa kumasisitimu ekutaurirana ane zvinodiwa zvekuvanzika zvakanyanya, senge Milstar yemauto eUS uye Advanced Extremely High Frequency (AEHF) masisitimu.
Satellite kutaurirana: kupa Broadband masevhisi uye kutsigira yakakwirira-kumhanya kufambisa data.
Radar masisitimu: anoshandiswa kune yakakwirira-resolution imaging radar uye moto control radar.
Tsvagiridzo yeSainzi: inoshandiswa pakuonekwa kwemhepo uye redhiyo yekuongorora nyeredzi.
Zvinetso nebudiriro:
Kunyangwe iwo mabhendi eQ-bhendi neEHF aine tarisiro yakakura yekushandisa, achiri kutarisana nemamwe matambudziko mukushandisa zvinoshanda:
Atmospheric attenuation: high-frequency signals inobatwa nemamiriro ekunze akadai sekunaya kwemvura panguva yekuparadzira, zvichikonzera kuderedzwa kwechiratidzo.
Tekinoroji yakaoma: yakakwira-frequency zvishandiso zvine yakakwira dhizaini uye yekugadzira zvinodiwa uye mutengo wakakwira.
Kusangana nematambudziko aya, vaongorori vari kugadzira epamberi modulation uye coding tekinoroji, pamwe nehungwaru hwemasuwo akasiyana zvirongwa zvekuvandudza kuvimbika kwesystem uye anti-kukanganisa kugona.
Mhedziso:
Q-bhendi uye EHF-bhendi inoita basa rakakosha mukutaurirana kwemazuva ano, radar uye tsvakiridzo yesainzi.
Nekufambira mberi kwetekinoroji, mashandisirwo eaya ma frequency band achawedzerwa, achipa mikana mitsva yekusimudzira kwakasiyana siyana.
