Canada's third-generation HFSWR forms the foundation of a maritime domain awareness system that provides enforcement agencies with real-time persistent surveillance out to and beyond the 200 nautical mile exclusive economic zone (EEZ). Cognitive sense-and-adapt technology and dynamic spectrum management ensures robust and resilient operation in the highly congested High Frequency (HF) band. Dynamic spectrum access enables the system to simultaneously operate on two frequencies on a non-interference and non-protected basis, without impacting other spectrum users. Sense-and-adapt technologies ensure that the system instantaneously switches to a new vacant channel on the detection of another user or unwanted jamming signal. Adaptive signal processing techniques mitigate against electrical noise, interference and clutter. Sense-and-adapt techniques applied at the detector and tracker stages maximize the probability of track initiation whilst minimizing the probability of false or otherwise erroneous track data.
加拿大的第三代高频地波雷达（HFSWR）构成了一个海域态势感知系统的基础，该系统为执法机构提供对200海里专属经济区及以外区域的实时持续监视。认知感知与自适应技术以及动态频谱管理确保了在高度拥挤的高频（HF）频段中实现强大且可靠的运行。动态频谱接入使该系统能够在不干扰和不受保护的基础上同时在两个频率上运行，而不会影响其他频谱用户。感知与自适应技术确保系统在检测到其他用户或有害干扰信号时能立即切换到新的空闲信道。自适应信号处理技术可减轻电噪声、干扰和杂波的影响。在探测器和跟踪器阶段应用的感知与自适应技术可在将虚假或错误跟踪数据的概率降至最低的同时，最大化跟踪起始的概率。
