Real-time simulation of an airborne radar for overwater approaches [PDF]

open access: yes
Software developed to provide a real time simulation of an airborne radar for overwater approaches to oil rig platforms is documented. The simulation is used to study advanced concepts for enhancement of airborne radar approaches (ARA) in order to reduce

Radar nonlinear multi-target tracking method with parallel PHD filter

open access: yesScientific Reports
Since probability hypothesis density (PHD) filters do not need explicit data association, they have recently been widely used in radar multi-target tracking (MTT). However, in existing PHD filters, sampling times are generally considered the same for all

Continuous Wavelet Transform and Hidden Markov Model Based Target Detection [PDF]

open access: yes, 2014
Standard tracking filters perform target detection process by comparing the sensor output signal with a predefined threshold. However, selecting the detection threshold is of great importance and a wrongly selected threshold causes two major problems ...
