在现代战争中具备有效指挥通信能力的部队将会取得明显的、也可能是决定性的优势。因此,就要有可靠的 VHF-FM 战术网无线电通信联络,即使面对敌方的电子对抗措施,也要保持畅通。为适应上述要求,美军开始了对 SINCGARS(单信道地面和机载系统)的研制。1978年签定了试制样机的合同。当时就已经认识到,目前战场上使用的背负式和车载式固定频率的战术电台(如 AN/PRC-77和 AN/VRC-12系列)是不能对抗当前的干扰技术的,因为固定频率容易窃听和遭到干扰。为克服这一点,SINCGARS 电台采用跳频技术作为电子反对抗措施。
Forces equipped with effective command and communication capabilities in the modern war will have obvious and possibly decisive advantages. Therefore, there is a need for a reliable VHF-FM tactical network radiocommunication link, even in the face of hostile electronic countermeasures. To meet the above requirements, the U.S. military started the development of SINCGARS (single-channel terrestrial and airborne systems). In 1978 signed a trial prototype contract. At that time, it was recognized that the tactical stations (such as the AN / PRC-77 and AN / VRC-12 series) with the fixed-frequency and vehicular fixed frequencies currently used on the battlefield are not capable of withstanding the current interference techniques because the fixed frequency is easily intercepted And was disturbed. To overcome this, SINCGARS stations employ frequency hopping as an electronic countermeasure.
