Frequency-Hopping

定义 Definition

跳频(frequency-hopping):一种无线通信/雷达技术,发送信号会按照预定序列在多个载波频率之间快速切换,以降低干扰与被窃听/被压制(干扰、阻塞、欺骗)的风险。(常见于“跳频扩频”FHSS)

例句 Examples

Bluetooth uses frequency-hopping to reduce interference.
蓝牙使用跳频来减少干扰。

In hostile environments, frequency-hopping spread spectrum can keep a radio link usable because a jammer must predict the hop pattern to disrupt it effectively.
在对抗性环境中,跳频扩频能让无线链路更难被有效干扰,因为干扰者必须预测跳频序列才能精准破坏通信。

发音 Pronunciation (IPA)

/ˈfriːkwənsi ˈhɑːpɪŋ/

词源 Etymology

frequency(频率) + hopping(跳跃式切换) 组成的复合词,字面意思是“在频率之间跳来跳去”。该术语在无线通信与军用/保密通信的发展中广泛使用,强调通过快速换频来提升抗干扰与隐蔽性。
