Learning to Detect with Constant False Alarm Rate

open access: yes2022 IEEE 23rd International Workshop on Signal Processing Advances in Wireless Communication (SPAWC), 2022
We consider the use of machine learning for hypothesis testing with an emphasis on target detection. Classical model-based solutions rely on comparing likelihoods. These are sensitive to imperfect models and are often computationally expensive.

Closed‐form expressions and statistical analysis of constant false alarm rate detection in multiple false target jamming condition

open access: yesIET Radar, Sonar & Navigation, 2022
Multiple false target jamming is an effective electronic attack measurement that will deteriorate the detection performance of radar constant false alarm rate (CFAR) detector, but its effects lack sufficient exploration. To solve the problem, an upgraded

A False Alarm Elimination Algorithm of Foreign Objects Debris Detection Based on Duffing Oscillator

open access: yesIEEE Access, 2022
The main challenge of foreign objects debris (FOD) monitoring based on millimeter-wave (MMW) radar is the interference of strong ground clutter. The clutter-map constant false alarm rate (CM-CFAR) method is commonly utilized for FOD monitoring, but ...

MIMO radar techniques: two-stage constant false alarm rate detection for fast-fluctuating targets

open access: yesThe Journal of Engineering, 2019
Here, the authors analyse a two-step constant false alarm rate (CFAR) detection problem in distributed sensor system (e.g. statistical multiple-input multiple-output (MIMO) radar) for fast-fluctuating targets (TS-AMF-II).

Statistical Properties of Energy Detection for Spectrum Sensing by Using Estimated Noise Variance

open access: yesJournal of Sensor and Actuator Networks, 2019
In energy detection for cognitive radio spectrum sensing, the noise variance is usually assumed given, by which a threshold is set to guarantee a desired constant false alarm rate (CFAR) or a constant detection rate (CDR).
