Radar matched filtering using the fractional fourier transform [PDF]

open access: yes, 2010
-A matched filter is the optimal linear filter for maximizing the signal to noise ratio (SNR) in the presence of additive noise. Matched filters are commonly used in radar systems where the transmitted signal is known and may be used as a replica to be ...

Intelligent Radar Jamming Recognition in Open Set Environment Based on Deep Learning Networks

open access: yesRemote Sensing, 2022
Jamming recognition is an essential step in radar detection and anti-jamming in the complex electromagnetic environment. When radars detect an unknown type of jamming that does not occur in the training set, the existing radar jamming recognition ...
