Detection of Unknown Radar Pulses Using Spiking Neural Networks
This article proposes to use spiking neural networks (SNNs) to detect multiple pulses in observation windows from a superheterodyne receiver. The method is described from encoding to postprocessing. New metrics are introduced to compare the proposed detection method to the energy detector (ED), to a detection based on difference Of boxes (DOB) filters ...

Asymptotically optimal detection of low probability of intercept signals using distributed sensors [PDF]
An asymptotically optimal technique for detection of low probability of intercept (LPI) signals using multiple platform receivers is proposed. This is a centralized detector unlike the commonly used decentralized decision fusion techniques and is an ...

This paper investigates the phase‐frequency response characteristics of frequency diverse array (FDA) radar on airborne warning and control system (AWACS) platforms and its deception mechanism against interferometric direction finders, aiming to address the vulnerability of AWACS to precise interception by passive direction‐finding systems due to poor ...

Antenna Array Beamforming for Low Probability of Intercept Radars [PDF]
A radar system's focus on low probability of intercept (LPI) performance has become increasingly important as systems designed for electronic support measures (ESM) and electronic counter measures (ECM) continue to become more prevalent.

Radar signal recognition exploiting information geometry and support vector machine
Aiming at the recognition of low‐probability‐of‐intercept (LPI) radar signals, a support vector machine (SVM)‐based algorithm is proposed, where the information geometry theory is utilised to optimise the kernel function of the SVM.

In physical-layer security and cryptography we are concerned with the security of the transmitted data, while in low probability of intercept (LPI) communication with protecting the privacy of the end users. In our recent publications related to LPI communications and radars over free-space optical (FSO) links we proposed to hide the constant-amplitude

This paper proposes a radar intra‐pulse modulation recognition method based on the transformer architecture, named RBViT. By designing multi‐scale input embeddings and introducing a novel position encoding based on radial basis functions (RBF), the algorithm significantly enhances recognition performance under a low signal‐to‐noise ratio (SNR ...
