全波收信机接收的频率范围包括了长波、中波和短波频段,适合远距离航行的船用收信业务,所以近年来船舶通信使用日益广泛。在设计全波收信机时,对收信机的主要性能,例如灵敏度、选择性、稳定性(包括船用的耐冲击振动)、频率读取精度和以抗阻塞抗干扰为出发的多信号特性等,都应该从长中短波的技术要求出发,统筹兼顾,制订完整合理的系统方案。
Full-wave receiver receives the frequency range includes long-wave, medium-wave and short-wave frequency band, suitable for long-distance navigation of the marine receiving business, so in recent years the increasingly widespread use of ship communications. In the design of full-wave receiver, the main performance of the receiver, such as sensitivity, selectivity, stability (including the ship’s shock-resistant vibration), the frequency of reading accuracy and resistance to anti-jamming multi-signal characteristics Etc., should start from the technical requirements of medium, short and medium waves, take all factors into consideration and formulate a complete and reasonable system solution.
