Design and Implementation of an Enhanced Matched Filter for Sidelobe Reduction of Pulsed Linear Frequency Modulation Radar [PDF]

open access: yesSensors, 2021
Pulse compression techniques are commonly used in linear frequency modulated (LFM) waveforms to improve the signal-to-noise ratios (SNRs) and range resolutions of pulsed radars, whose detection capabilities are affected by the sidelobes. In this study, a

A Frequency-Domain Adaptive Matched Filter for Active Sonar Detection [PDF]

open access: yesSensors, 2017
The most classical detector of active sonar and radar is the matched filter (MF), which is the optimal processor under ideal conditions. Aiming at the problem of active sonar detection, we propose a frequency-domain adaptive matched filter (FDAMF) with ...

Time-Range Adaptive Focusing Method Based on APC and Iterative Adaptive Radon-Fourier Transform

open access: yesRemote Sensing, 2022
In conventional radar signal processing, the cascade of pulse compression (i.e., matched filter) and Radon-Fourier transform (RFT) can extract the estimated scattering coefficient of the target in the range-velocity dimension through long-time coherent ...

Absorptive Weak Plume Detection on Gaussian and Non-Gaussian Background Clutter

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
For additive signals on Gaussian clutter, the optimal detector is a linear matched filter that is adapted to the known signal and the covariance of the background. This adaptive matched filter is widely used for gas-phase plume detection, even though the
