HFRadar

HFRadar is a system designed for the detection and tracking of high-frequency radar signals. It operates by passively listening for radio waves within a specific frequency range, typically from 3 to 30 megahertz. These frequencies are utilized by various types of radar systems, including over-the-horizon (OTH) radar, which can detect targets at very long distances by bouncing signals off the ionosphere.

The primary function of HFRadar is to identify the presence of these signals, determine their characteristics such as frequency, bandwidth, and modulation, and estimate their direction of arrival. This information can be used for a range of applications. In military contexts, HFRadar can provide early warning of aircraft or ships operating at long ranges, helping to build a situational awareness picture. It can also be used for electronic intelligence gathering, by analyzing the patterns and types of radar emissions.

In civilian applications, HFRadar technology can contribute to spectrum monitoring and management, ensuring efficient use of the radio frequency spectrum. It may also play a role in scientific research, such as studying atmospheric phenomena or ionospheric conditions that affect radio wave propagation. The development of HFRadar systems focuses on improving sensitivity, accuracy, and the ability to process complex signal environments.
