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.
CIFAR-10 is a set of images that can be used to teach a computer how to recognize objects. Since the images in CIFAR-10 are low-resolution (32x32), this dataset can allow researchers to quickly try different algorithms to see what works. CIFAR-10 is a labeled subset of the 80 Million Tiny Images dataset from 2008, published in 2009. When the ...
The 16-person journey mounted in September 2023 from Tarawa, Kirbati, a port near Howland Island, and the team’s unmanned submersible scanned 5,200 square miles of ocean floor.
This takes place before Doppler CFAR detection processing. A large modulation index is needed for practical reasons. A large modulation index is needed for practical reasons. Practical systems introduce reverse FM on the receive signal using digital signal processing before the fast Fourier transform process is used to produce the spectrum.
If you want to take a closer look at nature's wonders, you've come to the right place!Ian Granström, a photographer from Southern Finland, captures intimate wildlife images of foxes, birds, elk ...
Tens of thousands of California residents will decide whether to permanently relocate or rebuild their homes after the most destructive fires in Los Angeles’ history.
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.
