Techniques for homodyne dechirp-on-receive linearly frequency modulated radar

open access: yes, 2011
This thesis presents work done to extend and improve the operation of homodyne dechirp-on-receive linearly frequency modulated radars. First, an investigation of the effect of common phase errors on the point response function of the radar is ...

Generation of the ambiguity function for ultra wideband radar waveforms [PDF]

open access: yes, 1993
The Ambiguity Function is one of the tools used to study the suitability of waveforms for radar applications. An understanding of this function gives the radar engineer an insight into different radar waveforms and permits him to select the best design ...

Generating nonlinear FM chirp waveforms for radar. [PDF]

open access: yes, 2006
Nonlinear FM waveforms offer a radar matched filter output with inherently low range sidelobes. This yields a 1-2 dB advantage in Signal-to-Noise Ratio over the output of a Linear FM waveform with equivalent sidelobe filtering.

Quasi-Orthogonal Wideband Radar Waveforms Based on Chaotic Systems [PDF]

open access: yes, 2009
Many radar applications, such as those involving multiple-input, multiple-output (MIMO) radar, require sets of waveforms that are orthogonal, or nearly orthogonal.

Machine Learning Doppler‐Tolerant One‐Bit Radar Detectors

open access: yesIET Radar, Sonar & Navigation
Doppler‐tolerant waveforms are some of the most common radar waveforms used in practice. However, their deterministic and repetitive nature impedes control of mutual interference when multiple radars operate in close proximity. Noise radar technology may

OTFS Radar Waveform Design Based on Information Theory

open access: yesEntropy
In this work, we consider the waveform design for radar systems based on orthogonal time–frequency space (OTFS). The conditional mutual information (CMI), chosen as a promising metric for assessing the radar cognitive capability, serves as the criterion ...

Multi-criteria radar waveform design based on game theory

open access: yesXibei Gongye Daxue Xuebao
In complex battlefield environments, regarding the issues of weak anti-jamming capability, poor environmental adaptability, and resultant performance imbalance in radar waveforms designed based on single criterion, a radar waveform design method under ...

Online waveform selection for cognitive radar

open access: yesICASSP 2025 - 2025 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)
Designing a cognitive radar system capable of adapting its parameters is challenging, particularly when tasked with tracking a ballistic missile throughout its entire flight. In this work, we focus on proposing adaptive algorithms that select waveform parameters in an online fashion.
