Dual-Use Unimodular Sequence Design via Frequency Nulling Modulation
IEEE Access, 2018 This paper is focused on the design of the shared signal for a dual-use system with radar detection and communication functions. To achieve a good aperiodic autocorrelation property of the shared signal for radar detection, the lp-norm of the ...

IET Radar, Sonar &Navigation, Volume 18, Issue 10, Page 1919-1936, October 2024.The authors propose a novel waveform, namely, the orthogonal double V‐linear frequency modulation (ODV‐LFM) and corresponding simultaneous polarimetric measurement and pointwise linear and non‐linear processing methods. The proposed waveform can mitigate the influence of delay‐Doppler coupling and reduce the risk of false targets and ghosts in multiple‐

On the anti‐intercept features of noise radars
IET Radar, Sonar &Navigation, Volume 18, Issue 7, Page 1014-1035, July 2024.An evaluation of the related Low Probability of Detection, of Intercept and of Exploitation is presented for Continuous‐Emission Noise Radar waveforms with different operational parameters, that is, “tailored”, and with various “degrees of randomness”. The effect of “tailoring” is analysed with prospects for future work.

Sidelobe Suppression of Polyphase Coded Signal Using Different Filters
Journal of Engineering and Sustainable Development, 2012 This paper deals with different types of polyphase coded signals in terms of their correlation properties. The (Frank, P1, P2, P3 and P4) polyphase codes and the Iterative Reweight Least Square(IRLS) procedure were used in this work. Each polyphase code

Design of Binary Coded Pulse Trains with Good Autocorrelation Properties for Radar Communications
MATEC Web of Conferences, 2018 Finite length of sequences that are modulated both in phase and amplitude and have an ideal autocorrelation function (ACF) consisting of merely a pulse have many applications in control and communication systems.

IET Wireless Sensor Systems, Volume 14, Issue 3, Page 47-55, June 2024.In this article, the authors propose to use a smart binary phase‐coding (SBPC) method for a pulse compression radar as an electronic protection technique against repeater jamming. This approach further improves the target detection capability of modern radar systems, which use coherent integration in the receiver.

Joint transceive beamforming for multistatic radar system by semi‐definite relaxation method
IET Radar, Sonar &Navigation, Volume 18, Issue 5, Page 729-739, May 2024.The authors present a novel transmit and receive beamforming algorithm for the multistatic radar system that includes a common transmitter and multiple receivers. To ensure the balanced performance of the subsystems, the authors propose a weighted sum of the SINR optimisation problem to co‐design the transmit and receive beamforming. Abstract The joint

Information theoretic waveform design with applications to adaptive‐on‐transmit radar
IET Radar, Sonar &Navigation, Volume 18, Issue 1, Page 222-234, January 2024.The marginal Fisher information (MFI) metric is used to design waveforms for the sake of informationally optimal adaptive‐on‐transmit radar operation. The efficacy of the MFI waveform design and minimum mean square error (MMSE) estimation are experimentally demonstrated and extended into an adaptive and dynamic sensing paradigm.

Minimizing Peak Sidelobe Level in MIMO-SAR Waveform Design Using a 1.5-Entmax Sparse Loss
Remote SensingThe peak sidelobe level (PSL) of an orthogonal waveform set directly governs the range and azimuth ambiguities of synthetic aperture radar (SAR) images and is therefore a key figure of merit for the imaging quality of multiple-input multiple-output SAR ...
