跳频通信中,当敌方干扰导致通信中断率达20％时,通话质量下降,当通信中断率达40％时,通话质量严重恶化。实验证明采用“语音音节替代技术”后,能很大改善通话质量,当跳频中断率达到50％时,通话话音仍基本可懂,从而提高了跳频电台抗干扰能力。 In frequency-hopping communication, the call quality drops when the hostile interference causes the communication interruption rate to reach 20%. When the communication interruption rate reaches 40%, the call quality deteriorates seriously. Experiments show that the use of “voice syllabary alternative technology”, can greatly improve the call quality, when the frequency hopping interrupt rate of 50%, the call voice is still basically understand, thereby enhancing the frequency hopping anti-jamming capability of the radio.
