Radar-centric DFRC Signal Design: Overview and Future Research Avenues
Leida xuebao, 2023 During the confrontation of electronic systems, it is challenging to deal with the enemy’s comprehensive electronic weapons by simply combining electronic equipment, such as radar, communication, surveillance, and jammers. Hence, to meet the requirements

IET Power Electronics, EarlyView., 2023 This article presents a dual‐source novel nine‐level inverter (DSN2LI) featuring minimal devices. Utilizing eight switches, which include 2 bidirectional switching devices and 2 uneven dc links, the proposed DSN2LI generates nine levels. The DSN2LI employs the utilization of trinary geometric DC links.

Airborne Radar Anti-Jamming Waveform Design Based on Deep Reinforcement Learning
Sensors, 2022 Airborne radars are susceptible to a large number of clutter, noise and variable jamming signals in the real environment, especially when faced with active main lobe jamming, as the waveform shortcut technology in the traditional regime can no longer ...

Online unsupervised generative learning framework based radar jamming waveform design
IET Radar, Sonar & Navigation, 2023 The jamming effect on radar is dominated by the design of the jamming waveform directly. Traditional jamming waveforms are generated using the template‐based method and are not environmentally resilient. Without the precise radar centre frequency support,

Extended Target Recognition in Cognitive Radar Networks
Sensors, 2010 We address the problem of adaptive waveform design for extended target recognition in cognitive radar networks. A closed-loop active target recognition radar system is extended to the case of a centralized cognitive radar network, in which a generalized ...

Properties of the MIMO radar ambiguity function [PDF]
, 2008 MIMO (multiple-input multiple-output) radar is an emerging technology which has drawn considerable attention. Unlike the traditional SIMO (single-input multiple-output) radar, which transmits scaled versions of a single waveform in the antenna elements ...

Towards Dual-functional Radar-Communication Systems: Optimal Waveform Design [PDF]
, 2017 We focus on a dual-functional multi-input-multi-output (MIMO) radar-communication (RadCom) system, where a single transmitter communicates with downlink cellular users and detects radar targets simultaneously.

Waveform considerations in space-variant optical processors [PDF]
, 1978 The use of coded waveforms in space-variant optical signal processors using coordinate transformations is considered. It is shown that nonlinear transmitted coded signals must be used with such a processor and that this results in novel waveform design ...
