Incoherent Integration Detection Method of Airborne Phased Array Radar in a Multipath Environment
Airborne phased array radar (PAR) suffers from multipath problems when flying over a calm sea surface. The existence of a multipath phenomenon will cause the electromagnetic echo of the same target to be reflected back to the airborne PAR from two paths,

We address the suppressing problem of smeared spectrum (SMSP) jamming from the mixed signal received by the radar. To this end, we resort to the time-frequency analysis algorithm and give the concrete expression formula of the short-time Fourier ...

Chaff identification method based on Range‐Doppler imaging feature
Chaff is widely used in electronic countermeasures as an effective passive jamming method. This study proposes a chaff identification method that integrates the distribution of distance, Doppler frequency, and power in Range‐Doppler imaging.

Signals and Signal Processing for the Electrophysiologist [PDF]
In part II of this series, using the background covered in part I on electrogram acquisition and signal processing, we discuss potential errors in mapping because of artifact or inappropriate filtering of signals that may lead to unsuitable selection of ablation sites. ### Saturation Artifact If a 3-mV peak signal is being amplified at a gain of 5000,

Convolutional neural networks for radar HRRP target recognition and rejection
Robust and efficient feature extraction is critical for high-resolution range profile (HRRP)-based radar automatic target recognition (RATR). In order to explore the correlation between range cells and extract the structured discriminative features in ...

Two-Stream Deep Fusion Network Based on VAE and CNN for Synthetic Aperture Radar Target Recognition
Usually radar target recognition methods only use a single type of high-resolution radar signal, e.g., high-resolution range profile (HRRP) or synthetic aperture radar (SAR) images. In fact, in the SAR imaging procedure, we can simultaneously obtain both
