Distributed massive UAV jamming optimization algorithm with artificial bee colony

open access: yesIET Communications, Volume 17, Issue 2, Page 197-206, January 2023., 2023
Abstract With the massive application of unmanned aerial vehicles (UAVs) in disaster relief, fire protection, security and other fields, jamming countermeasures to UAVs in airports and competition venues have become the core link of security in high‐level matches and important places. The existing jamming sources are mainly single point jamming. Due to

Research on main‐lobe deceptive jamming against FDA‐MIMO radar [PDF]

open access: yesIET Radar, Sonar & Navigation, 2021
AbstractA multiple‐input multiple‐output (MIMO) radar with frequency diverse array (FDA) produces a range‐angle‐dependent steering vector, which can suppress the deceptive jamming in joint range‐angle domain. This in turn complicates the task of radar jamming. With the emergence and development of digital radio frequency memory (DRFM), radar electronic
