Constant false alarm rate (CFAR) detection is a common form of adaptive algorithm used in radar systems to detect target returns against a background of noise, clutter and interference. [ 1 ] Principle
Passive radar (also referred to as parasitic radar, passive coherent location, passive surveillance, and passive covert radar) is a class of radar systems that detect and track objects by processing reflections from non-cooperative sources of illumination in the environment, such as commercial broadcast and communications signals.
Automatic target recognition (ATR) is the ability for an algorithm or device to recognize targets or other objects based on data obtained from sensors.. Target recognition was initially done by using an audible representation of the received signal, where a trained operator who would decipher that sound to classify the target illuminated by the radar.

NOAA, Kraken Robotics and ThayerMahan conducted a joint technology demonstration in 2019, [11] where synthetic-aperture sonar was one of the technologies demonstrated. Detection of carbon dioxide gas seeps has been using synthetic-aperture sonar coupled with advanced signal processing has been proven possible, and is an ongoing research topic. [12]
The list of top 10 baby names shouldn’t be all too surprising, the Health Department said, with most appearing on the list in the past few years.. Sofia, for example, crawled its way into the No ...
The Indianapolis Colts could show up to the stadium on Sunday with nothing to play for. Or the scenario may call for a victory so they can remain alive in the AFC playoffs.
Track algorithm operation depends upon a track file, which contains historical track data, and a computer program that periodically updates the track file. [ 3 ] Sensors information (radar, sonar, and transponder data) is provided to the track algorithm using a polar coordinate system , and this is converted to cartesian coordinate system for ...
