Towards an accurate radar waveform recognition algorithm based on dense CNN
Multimedia Tools and Applications, 2020Existing algorithms for radar waveform classification currently exhibit the lower recognition accuracy, especially at the lower signal to noise ratio (SNR) environment. To remedy these flaws, this paper proposes an accurate automatic modulation classification algorithm based on dense convolutional neural networks (AAMC-DCNN).

Relationship of target recognition performance and radar waveform parameters
Journal of Electronics (China), 2011Target recognition performance can be affected by radar waveform parameters. In this paper, we established rigorous relationship between target recognition efficiency and the parameters of a repeatedly transmitted waveform. It is based on Kullback-Leibler Information Number of single observation (KLINs), which measures the dissimilarity between targets

Radar Waveform Recognition based on Deep Residual Network
2019 IEEE 8th Joint International Information Technology and Artificial Intelligence Conference (ITAIC), 2019This article presents our initial results in deep learning for the complex multiple radar waveforms recognition. The method is composed of time-frequency analysis and deep residual network (ResNet). Firstly, we transform one-dimensional radar signals into two-dimensional time-frequency images (TFIs), which can reveal more characteristics of the signals.

Radar Signal Waveform Recognition Based on Convolutional Denoising Autoencoder
2019To solve the problem of the low recognition rate of the existing methods at low signal-to-noise ratio (SNR), we propose a novel method of radar signal waveform recognition. In this method, we extract the time-frequency images (TFIs) of radar signals through Cohen class time frequency distribution. Then, we introduce convolutional denoising autoencoder (

Use of wideband waveforms for target recognition with surveillance radars
Record of the IEEE 2000 International Radar Conference [Cat. No. 00CH37037], 2002A long range target recognition system has been developed using a high range resolution mode in a surveillance radar. The radar performs normal air surveillance but on targets of interest a wideband waveform is used in a few pulses of the normal dwell. These pulses are processed to yield high resolution range profiles of the target.

Automatic Radar Waveform Recognition Based on Deep Convolutional Denoising Auto-encoders
Circuits, Systems, and Signal Processing, 2018Aimed at the deficiency of traditional feature extraction techniques in radar emitter recognition, a novel deep feature extraction and recognition architecture is proposed. To fit into the model, the time-domain emitters are transformed into unique time-frequency images correspondingly.

Target recognition with high-fidelity target signatures and adaptive waveforms in MIMO radar
2015 IEEE 6th International Workshop on Computational Advances in Multi-Sensor Adaptive Processing (CAMSAP), 2015In previous work, we have demonstrated the advantage of a closed-loop radar system that provides a feedback loop from radar receiver to transmitter in a widely separated multi-input multi-output (MIMO) radar scenario. The results for widely separated MIMO radar showed performance benefit when exploiting spatial diversity with adaptive waveforms ...

Adaptive single-tone waveform design for target recognition in cognitive radar
IET Conference Publications, 2009Cognitive radar is a recently proposed system concept, one of whose most important characteristics is the closed-loop operation. The feedback structure from the receiver to the transmitter enables the optimization of transmission waveforms based on the latest knowledge about targets and environments.
