The weapon target assignment (WTA) problem is the crucial decision support in Command & Control (C2). In classic WTA model, point-to-point saturation salvo has a low efficiency-cost ratio when swarming targets, which have advantage of casualty, cost and recyclable, become major operational units. constraint less studied for intention decision-maker. this paper, constrained multi-objective (CMWTA) model formulated area targets. optimization objectives are minimizing collateral damage resource...
The maneuvering decision in beyond visual range (BVR) is very important for aircraft with middle-range missiles and advanced avionics. A model attack region threat proposed to describe the air combat problem. Then a new prediction control (MPC) scheme solve real-time trajectory optimization problem introduced numerical solution direct multiple shooting (DMSM) method proposed. simulation shows that this efficient decision.
A single-layer ±45° dual-polarized directional array antenna for millimeter wave (mm-wave) applications is designed in this communication. Based on the theory of orthogonal circularly polarized (CP) multiplexing, two ports a series-fed dual CP are fed with equal amplitudes, and can radiate linearly polarization orientations through adjustment feeding phase difference. As simultaneously excited, achieve radiation. In addition, cross-polarization level be effectively suppressed by placing...
Abstract: Aiming at the problem that sequential diagnosis strategy optimization techniques for complex avionics systems are currently difficult to obtain optimal solutions quickly and effectively, this paper proposes an improved Quasi-Depth First Search (QDFS) algorithm based on Rollout optimize design of strategies. The determines a test in two steps. Firstly, is used construct temporary diagnostic tree with selected as vertex, then "evaluation function" QDFS calculate compare constructed...
Aiming at the specific texture property which exists in cipher image with implementation of encryption algorithm ECB mode, an efficient diffusion mechanism to eliminate phenomenon is proposed. By analyzing reasons for phenomenon, pseudo-random sequences were adopted permute bytes identical plaintext block before encryption, it can be effectively removed. The security technique has been analyzed using PSNR, plain sensitivity test and statistical analysis. Experimental results verify that this...
