本文论述了电子支援措施(ESM)的系统特性对海军行动的重要性。这些特性包括信号检测灵敏度、频率测量、角精度以及识别发射源的密集脉冲背景中混入其他特殊发射信号的基本能力。本文讨论了以在国防预算缩减条件下所能承受的代价,使未来的设备能够满足不断扩大的要求时设计人员所面临的挑战问题。 This article discusses the importance of the systematic nature of electronic support measures (ESMs) to naval operations. These features include signal detection sensitivity, frequency measurement, angular accuracy, and the basic ability to identify the presence of other special transmitted signals in the dense pulse background of the transmitting source. This article discusses the challenges that designers face in meeting the ever-expanding requirements of future devices at the price that can be sustained under reduced defense budgets.
