Passive radar in the high frequency band

open access: yes2008 IEEE Radar Conference, 2008
Passive radar systems using emitters of opportunity for target detection and tracking have received significant interest recently, especially those which exploit frequency modulated (FM) radio stations and TV transmitters as signal sources. This paper is concerned with passive radar systems that utilize signal sources in the high frequency (HF) band (3-

High Frequency Radar

2021
High frequency (HF) radars operate at radio frequencies between 3 and 30 MHz, where electromagnetic waves have the ability to propagate along the ocean surface and therefore to obtain information beyond the horizon. All the information measured by a HF radar corresponds to physical parameters of the upper couple of meters of the ocean surface.

High-frequency radar simulations

Proceedings of the IEEE Sixth Working Conference on Current Measurement (Cat. No.99CH36331), 1999
A simulation of the University of Michigan's Multifrequency Coastal Radar (MCR) has been applied under various scenarios to compare the performance of beam forming and direction finding techniques for bearing determination. The MCR system is a phased array radar that operates at four distinct frequencies in the high frequency (HF) range in order to ...
