Online unsupervised generative learning framework based radar jamming waveform design

open access: yesIET 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,

Constrained Radar Waveform Design for Range Profiling [PDF]

open access: yesIEEE Transactions on Signal Processing, 2021
Range profiling refers to the measurement of target response along the radar slant range. It plays an important role in automatic target recognition. In this paper, we consider the design of transmit waveform to improve the range profiling performance of radar systems.

Extended Target Recognition in Cognitive Radar Networks

open access: yesSensors, 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 ...

Deep Radar Waveform Design for Efficient Automotive Radar Sensing [PDF]

open access: yes2020 IEEE 11th Sensor Array and Multichannel Signal Processing Workshop (SAM), 2020
In radar systems, unimodular (or constant-modulus) waveform design plays an important role in achieving better clutter/interference rejection, as well as a more accurate estimation of the target parameters. The design of such sequences has been studied widely in the last few decades, with most design algorithms requiring sophisticated a priori ...
