Mayelana nalolu hlelo lokusebenza
Ukuze ECM, lolu hlelo ukubala J / S ratio ngenxa yokuma-off jammer (SOJ) isimo. Kulokhu, lo jammer kuba kwenye indawo ngaphandle kwelitshe. Nakuba ilitshe lingaba ugongolo main of the antenna radar, lo jammer akhanye amandla engena sidelobes. Njengoba isibonelo, kube radar ethungatha, faka amandla kW antenna inzuzo DB, futhi UMA umkhawulodonsa in MHz. Bese ufaka esiphambanweni ndiza endaweni Sectional e m ^ 2 futhi uhla km.
Okulandelayo, kube jammer abagibele ngamandla Transmitter in kW esingaphezu bandwidth in MHz futhi banikezwe antenna inzuzo in dB kude kusukela radar in km kanye sidelobe in dB izinga antenna radar.
Ngokwesibonelo, Ungiyingenisangoma Pt = 100, Gr = 35, Br = 1, A = 4, R = 3, PJ = 1, Bj = 20, GJ = 10, Rj = 10, & SL = 20. Ngokuyinhloko, ukubaluleka kwakho for J / S (SOJ) kufanele -14,0 dB.

Kubuyekezwe ngo-
Ukuphepha kuqala ngokuqonda ukuthi onjiniyela baqoqa futhi babelane kanjani ngedatha yakho. Ubumfihlo bedatha nezinqubo zokuphepha zingahluka kuye ngokusebenzisa kwakho, isifunda, nobudala. Unjiniyela unikeze lolu lwazi futhi angalubuyekeza ngokuhamba kwesikhathi.
Ayikho idatha eyabiwe nezinkampani zangaphandle
Funda kabanzi mayelana nendlela onjiniyela abaveza ngayo ukwabelana
Ayikho idatha eqoqiwe
Funda kabanzi mayelana nokuthi onjiniyela bakuveza kanjani ukuqoqwa
