This paper presents a rule-based intelligent guidance strategy for autonomous pursuit of mobile targets by unmanned aerial vehicles (UAVs) in an area with threats, obstacles, and restricted regions. The probabilistic threat exposure map (PTEM) is used as the mathematical formulation operation to make decisions based on set defined rules. rules are developed three objectives order priority as: 1) avoid obstacles/restricted regions; 2) maintain target proximity; 3) minimize UAV level. A...

This study proposes a new approach to creating virtual flight test environment by integrating digital twin of an iron bird rig with engineering simulator. Generating twins for rigs in aviation is rare and innovative approach. The simulator used this incorporates real hands-on throttle stick provide pilots realistic experience. A validated trainer aircraft, fully equipped encompassing hydraulic, mechanical, control, landing gear systems, was as the basis generating its twin. then update...

Aiming to address the vulnerability of non-stealth aircraft radar detection due inherent design limitations, this paper proposes a method generate maneuvers that reduce an aircraft’s cross-section (RCS) value below specified threshold. The proposed employs control barrier functions and leverages relationship between inputs RCS. Due confidentiality concerns, required RCS database for F-16 was generated through analyses performed using created geometry. results are compared with virtual path...

A strategy is presented for an unmanned aerial vehicle (UAV) to follow a moving target in area the probabilistic threat exposure map of which assumed be known based on priori data. defined risk multiple sources as function position. The generates speed and heading angle commands within dynamic constraints UAV. There are three main objectives order priority: 1) All restricted areas avoided. 2) UAV stays proximity by prespecified distance. 3) total level minimized. During pursuit, their time...

In this paper, we will introduce a probabilistic solution to the problem of trajectory planning for UAV ying in dynamic environment. By environment mean that map is time-variant i.e probability becoming disabled at given location might be changing over time. Probabilistic dened as risk exposure sources threat function time and position. This case when likelihood and/or obstacles their position priori known.

In this paper, we present a cooperative strategy for multiple UAVs under communication constraints to follow moving target in an area with threat sources. The main goals of the are, (i) ensure that do not enter restricted regions (ii) maintain pursuit by at least one UAV (iii) minimize exposure level each (iv) relative distance between within range, and (v) generate commanded heading speed dynamic UAV. Exposure is modelled using multidimensional Gaussian Law. When are they send their own...

The objective in this paper is to pursue a target by multiple UAVs when the moves an area with threats, obstacles and restricted areas. In pursuit there are two conflicting objectives: (i) all stay close (ii) avoid restricted-areas/obstacles total threat exposure level minimized. This develops formulation quantify trade-off between these objectives cooperative manner providing proximity circles that how what formation should follow target. These calculated using gradient search approach,...
