Codesign of Beam Pattern and Sparse Frequency Waveforms for MIMO Radar

International Journal of Antennas and Propagation, 2015
Multiple-input multiple-output (MIMO) radar takes the advantages of high degrees of freedom for beam pattern design and waveform optimization, because each antenna in centralized MIMO radar system can transmit different signal waveforms.

Joint waveform design and resource allocation strategy for cognitive radar target situation awareness

IET Radar, Sonar & Navigation
Traditional radar systems use fixed patterns and constant electromagnetic wave transmission to illuminate targets, but they often do not effectively use prior information about targets and consume significant radar resources.

Optimum Waveform Selection for Target State Estimation in the Joint Radar-Communication System

IEEE Open Journal of Signal Processing
The widespread usage of the Radio Frequency (RF) spectrum for wireless and mobile communication systems generated a significant spectrum scarcity. The Joint Radar-Communication System (JRCS) provides a framework to simultaneously utilize the allocated ...

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 ...
