VSWR, kugaruka gutakaza (RL), kwerekana imbaraga, n'imbaraga zoherejwe

Isano iri hagati yumubyigano uhagaze wa VSWR (VSWR), igihombo cyo kugaruka (RL), imbaraga zigaragaza, nimbaraga zoherejwe zirahuzwa binyuze muri coefficient (Γ). Hano haribintu byingenzi byingenzi hamwe nintambwe zo guhinduka:

### ** Inzira Nkuru **
1. ** Coefficient yo gutekereza (Γ) **:

\ Gamma = \ frac {\ inyandiko {VSWR} - 1} {\ inyandiko {VSWR} + 1}

2. ** VSWR ** kuva Γ:

\ inyandiko {VSWR} = \ frac {1 + | \ Gamma |} {1 - | \ Gamma |}

3. ** Garuka Igihombo (RL) ** muri dB:

\ inyandiko {RL (dB)} = -20 \ log_ {10} (| \ Gamma |)

4. ** Imbaraga Zigaragaza (%) **:

P _ {\ inyandiko {kwerekana}} = | \ Gamma | ^ 2 \ inshuro 100 \%

5. ** Imbaraga zoherejwe (%) **:

P _ {\ inyandiko {trans}} = \ ibumoso (1 - | \ Gamma | ^ 2 \ iburyo) \ inshuro 100 \%

### ** Intambwe zo Guhindura **
#### ** 1. Guhera kuri VSWR **:
- Kubara Γ:

\ Gamma = \ frac {\ inyandiko {VSWR} - 1} {\ inyandiko {VSWR} + 1}

- Koresha Γ kugirango ubone RL, imbaraga zigaragaza, nimbaraga zoherejwe ukoresheje formula iri hejuru.

#### ** 2. Guhera hamwe no gutakaza igihombo (RL muri dB) **:
- Kubara Γ:

| \ Gamma | = 10 ^ {- \ inyandiko {RL} / 20}

- Koresha Γ gushaka VSWR, imbaraga zigaragaza, nimbaraga zoherejwe.

#### ** 3. Guhera hamwe nimbaraga zigaragazwa / zoherejwe **:
- Kuri ** imbaraga zigaragaza ** (\ (P _ {\ inyandiko {reba}} \)):

| \ Gamma | = \ sqrt {\ frac {P _ {\ inyandiko {reba}}} {100}}

- Kuri ** imbaraga zoherejwe ** (\ (P _ {\ inyandiko {trans}} \)):

| \ Gamma | = \ sqrt {1 - \ frac {P _ {\ inyandiko {trans}}} {100}}

- Koresha Γ kubara VSWR na RL.

### ** Imbonerahamwe y'urugero **
| ** VSWR ** | ** Garuka Igihombo (dB) ** | ** Imbaraga Zigaragaza (%) ** | ** Imbaraga zoherejwe (%) ** |
| ---------- | ---------------------- | ------------------------- | --------------------------- |
| 1.0 | (Umukino utunganijwe) | 0% | 100% |
| 1.5 | 14.0 dB | 4% | 96% |
| 2.0 | 9.5 dB | 11.1% | 88.9% |
| 3.0 | 6.0 dB | 25% | 75% |

### ** Ingingo z'ingenzi **
- A ** VSWR ya 1: 1 ** bivuze ko nta bitekerezo (Γ = 0, RL = ∞).
- ** Hejuru ya VSWR ** cyangwa ** RL yo hepfo ** yerekana imbaraga zigaragara.
- ** Imbaraga zoherejwe ** zirenze iyo VSWR ≈ 1.
