Adaptive waveform design for imaging MIMO radar systems [PDF]
, 2022 6 S.One limitation of MIMO imaging radar systems is the waveform diversity available for the transmitters. Indeed, different properties for the transmitted signals, such as orthogonality and Doppler tolerance, are required in order to obtain good imaging

Modeling Envisat RA-2 waveforms in the coastal zone: case-study of calm water contamination [PDF]
, 2010 Radar altimeters have so far had limited use in the coastal zone, the area with most societal impact. This is due to both lack of, or insufficient accuracy in the necessary corrections, and more complicated altimeter signals. This paper examines waveform

Neural Networks for Radar Waveform Recognition [PDF]
Symmetry, 2017 For passive radar detection system, radar waveform recognition is an important research area. In this paper, we explore an automatic radar waveform recognition system to detect, track and locate the low probability of intercept (LPI) radars. The system can classify (but not identify) 12 kinds of signals, including binary phase shift keying (BPSK ...
