Study on CA-CFAR Algorithm Based on Normalization Processing of Background Noise for HI of Optical Fiber

Photonic Sensors, 2018
Optical fiber pre-warning system (OFPS) is often used to monitor the occurrence of disasters such as the leakage of oil and natural gas pipeline. It analyzes the collected vibration signals to judge whether there is any harmful intrusion (HI) events.

The adaptive constant false alarm rate for sonar target detection based on back propagation neural network access

IET Signal Processing, 2023
With oceanic reverberation and a large amount of data being the main sources of interference for underwater acoustic target detection, it is difficult to obtain a more robust detection performance by relying on the traditional constant false alarm rate ...

A constant-false-alarm-rate algorithm [PDF]

, 1992
The constant-false-alarm-rate (CFAR) detection algorithm is used for the detection of an optical target in an image dominated by optical clutter. The algorithm can be used for many aerial images when a clutter-subtraction technique is incorporated.

A Two‐Stage Genetic Algorithm for Joint Optimization of PAPR and PSLR for Precise Signal Reconstruction in OFDM‐ISAC Systems

IET Communications, Volume 20, Issue 1, January/December 2026.
This paper presents a two‐stage genetic algorithm based waveform design framework for OFDM integrated sensing and communication (ISAC) systems. In Stage‐1, a multi‐objective genetic algorithm jointly optimizes the peak‐to‐average power ratio (PAPR) and peak sidelobe level ratio (PSLR) under forward error correction and reserved subcarrier constraints ...

Robust Beamforming for ISAC Systems via Probability of Detection Optimisation

Electronics Letters, Volume 62, Issue 1, January/December 2026.
We propose a two‐step robust beamforming design for ISAC that maximises multi‐target detection probability while satisfying multi‐user SINR and per‐antenna power constraints. A sensing‐only Riemannian optimisation on the oblique manifold shapes the transmit covariance, followed by SDR‐based reconstruction to enforce communication guarantees ...
