Kakawanda siyana ari Radio uye Terevhizheni

Frequency Range - izwi iro zvinowanzoshandiswa mararamiro mumuviri unyanzvi nyaya, kunyanya mune zvemagetsi. Pasi pfungwa iyi zvinonzwisiswa sezvo uchishandisa siyana zano uye akazvitsaurira redhiyo basa kuti nhepfenyuro imwe Frequency siyana. Uye tinogona kutaura pamusoro Kuparara ose redhiyo Frequency siyana.

Mitemo International mukanyatsochengeta waidzora kushandiswa akasiyana Nhepfenyuro yeredhiyo gadziriro (kusanganisira kuongorora), zvakawanda yakajeka. Izvi zvinosiyana kudiwa kuitira interoperability dzakasiyana gadziriro uye kushanda kuparadza chipingaidzo.

Maererano Radio Regulation, nzvimbo Pasi rakakamurwa ruwa guru matatu. Wokutanga zvinosanganisira Europe, Kishi, Russia, Mongolia uye Africa. Wechipiri - nharaunda America (zvose North uye South). Chechitatu - South uye South-East Asia, Australia, yePacific nharaunda. In neimwe nzvimbo - kuparadzirwa yayo redhiyo maitikiro zvisungo.

Nokuti nokushanda Satellite yokukurukurirana murau kunopa maitikiro nezvisungo vane zviratidzo: L, S, C, X, Ku, Ka, K anoda kubva 1452 MHz kusvika 86,0 GHz. Ruzhinji Satellite gadziriro uchishanda mapoka C uye Ku. Range Ka vachishingaira yakatanga muna Europe uye America, asi munyika yedu haina zvikuru kushandiswa.

The kanyanga kunyatsoshanda ichitovimbawo uwandu wavelengths kuti anoenderana dhayamita yacho kanyanga. With kuwedzera kakawanda, ari wavelength iri shoma (tsika idzi inversely Proportional) uye guru kanyanga haisi kunodiwa kugamuchira dzakakwirira maitikiro anonongedzera. Sezvo kakawanda siyana vakagamuchirazve ane kanyanga kukura 2.5-4.5 metres, uye nokuda kugamuchira aida chinozunguzirwa bhendi K kanyanga saizi -. Only 10-15 masendimita With zvakaenzana antennas kushanda mukuru siyana, vane fuma yepamusorosoro.

In nomumwe nhepfenyuro wokutepfenyurisa chiteshi anewo ayo Frequency siyana. Pane kupatsanura redhiyo mafungu pamusoro siyana uye wavelength. Maererano chinozunguzirwa ichi ndiwo:

- Dekametricheskie aine wavelength pakati sezvakarayirwa 10 000-100 000 makiromita, vane frequencies dzinoiswa se zvikuru pasi (3 - 30 Hz).

- Megametricheskie (wavelength - 000 makiromita 1000-10), kakawanda siyana - 300 Hz.

- Gektokilometrovye (ane kureba 100-1,000 kilometers) chokuita ultralow maitikiro (3000 Hz).

- Extra refu (kureba - 10-100 kilometers) - pasi kwazvo (30 kHz).

- urefu (kureba 1-10 kilometers) - pasi (kusvika 300 kHz).

- Avhareji (urefu 100-1000 metres) - mids kusvika 3000 kHz.

- Short, une kureba 10-100 metres - ndicho ainzi .. yakakwirira maitikiro (maitikiro 30 MHz).

- Ultrashort kana mita (urefu 1-10 metres), mukuru kwazvo (kusvika 300 MHz).

- Decimeter (urefu 10-100 cm) uye Ultra-soro, kusvikira 3000 MHz.

- sendimita (1-10 masendimita urefu), super-soro (30 GHz).

- millimeter (urefu 1-10 mm), mukuru kwazvo (kusvika 300 GHz).

300-3000 GHz Frequency siyana zvinoreva t. N. hyper-soro Frequency zvenguva.

In kwokutanga nzendo kukura redhiyo mafungu kushandiswa kunyanya refu uye nakisa kumberi. Asi vari kuparadzira pamusoro panyika, wefodya zvakasimba, zvaida zvinotakura simba. Yakadzikama kugamuchira rinoitwa pasi svikiro wave, asi kwavari zvakaoma nechokwadi nokupfuuridzirwa kure, uye anoshandisa chikuva ichi, zvikurukuru redhiyo womunharaunda ine nharaunda anoverengeka zana makiromita.

Orangy zvinopa zvikuru chikuva, asi pasi ruzha uye chiratidzo kusarurama. Ivo anoshandiswa zvikurukuru mhepo uye nepagungwa kufamba uye chokuita nemigwagwa mitsetse.

The chikuru mukana mukuru-kakawanda neeSultan - mukana kushandisa kanyanga ane kukura vari akafanana wavelength, nokuita kuti mwaranzi unoshanda chete pasi ichi. Kuvaka kure muchikurukurirana gadziriro kwakavakirwa Mashoko mafungu pamberi, yakaitwa zvinobvira nokushandiswa kubata pasi satellites.
