Multiple Target, Multiple Type Filtering in the RFS Framework

open access: yes, 2019
A Multiple Target, Multiple Type Filtering (MTMTF) algorithm is developed using Random Finite Set (RFS) theory. First, we extend the standard Probability Hypothesis Density (PHD) filter for multiple types of targets, each with distinct detection ...

Clutter Modeling and Characteristics Analysis for GEO Spaceborne-Airborne Bistatic Radar

open access: yesRemote Sensing
The spaceborne-airborne bistatic radar (SABR) system employs a spaceborne transmitter and an airborne receiver, offering significant advantages, such as wide coverage, outstanding anti-stealth capabilities, and notable resistance to jamming. However, SABR operates in a downward-looking configuration, and due to the separation of the transmitter and ...
