“…Thus in the same distance between the radar and the stealth aircraft, the detecting probability is varied on different azimuth. 1,13,25 From the standpoint of the low observability trajectory planning, one means of radar tracking avoidance is to change the relative aspect to the radar into a low observable one, thereby a lower RCS value of the aircraft makes itself stealth to the radar. The aircraft changes the relative aspect by attitude and heading angle control.…”

“…Small RCS should make trouble for radar detecting and tracking. The stealth aircrafts, such as X-45, X-47A, X-47B, X-48B, and Europe NEURON, which have low RCS of majority circumferential curve and several narrow peaks, 1 are preferred candidates as executors for dangerous and tough mission in a rigorous surveillance radar network. A stealth aircraft often flies at a high altitude considering flight time, fuel consumption and risk.…”

The stealth aircraft, studied in this article, plans a low observability trajectory to evade radars tracking, considering probability of detection and system constraints. An elaborate framework of planning low observability trajectory, which integrated the models of the stealth aircraft and radars, the theory of multi-phase optimal control and the algorithms of adaptive pseudospectral method, is presented in this article. The constraints and temporal features of low observability trajectory are modeled. The optimal objectives of the flight time, the total fuel consumption, and stealth are defined and synthesized. The trajectory planning problem then was formulated as a multi-objective multi-phase optimal control problem, which can availably grasp the radar tracking features to ensure safety in the whole flight process. A hybrid heuristic adaptive pseudospectral method is developed to solve the trajectory planning problem. The novel algorithm integrates prior knowledge, error estimate and solution regularity for adaptive strategy, which improves computational efficiency and convergence speed. The results of experiments show that the proposed method is feasible and the radar tracking features are effectively utilized to optimize the comprehensive efficiency of penetration.

This paper studies the radar cross section (RCS) of carrier electronic warfare airplanes. Under the typical naval operations section, the mathematical model of the radar wave's pitch angle incidence range analysis is established. Based on the CATIA software, considering dynamic deflections of duck wing leading edge flaps, flaperons, horizontal tail, and rudder, as well as aircraft with air-to-air missile, anti-radiation missile, electronic jamming pod, and other weapons, the 3D models of carrier electronic warfare airplanes Model A and Model B with weapons were established. Based on the physical optics method and the equivalent electromagnetic flow method, by the use of the RCSAnsys software, the characteristics of carrier electronic warfare airplanes' RCS under steady and dynamic flights were simulated under the UHF, X, and S radar bands. This paper researches the detection probability of aircraft by radars under the condition of electronic warfare, and completes the mathematical statistical analysis of the simulation results. The results show that: The Model A of carrier electronic warfare airplane is better than Model B on stealth performance and on discover probability by radar detection effectively. ª 2015 The Authors.

“…Stealth unmanned aerial vehicles (UAVs), such as X-45, X-47A, X-47B, X-48B, and Europe Neuron, which have low radar cross section (RCS) of the majority circumferential curve and several narrow peaks 2 , are preferred candidates as the leading actor to win the radar game in an integrated air defense system. However, stealth UAVs still have several RCS peaks; these peaks are high observability aspects for radar detecting and tracking.…”

In this paper, problem of planning tactical trajectory for stealth unmanned aerial vehicle (UAV) to win the radar game is studied. Three principles of how to win the radar game are presented, and their utilizations for stealth UAV to evade radar tracking are analysed. The problem is formulated by integrating the model of stealth UAV, the constraints of radar detecting and the multi-objectives of the game. The pseudospectral multi-phase optimal control based trajectory planning algorithm is developed to solve the formulated problem. Pseudospectral method is employed to seek the optimal solution with satisfying convergence speed. The results of experiments show that the proposed method is feasible and effective. By following the planned trajectory with several times of switches between exposure and stealth, stealth UAV could win the radar game triumphantly.
