Based on the Monte Carlo method, the quasi random number was introd.
研究并建立了海面舰船的红外理论模型,较为完整地考虑了周围环境对物体及物体各部分之间的相互作用,包括太阳辐射、海/天背景辐射、海/空气的对流,以及船体各部分的传导和相互辐射(考虑多次反射);同时考虑了舰船内舱对船壁的辐射和对流作用;采用蒙特卡洛方法,引入准随机数解决了复杂几何结构表面非漫反射灰体的辐射计算。
Method of symmetric NAT traversal of UDP through NATs based on guess-pseudorandom;
基于端口准随机猜测的UDP穿越Symmetric NAT的方法
Due to High-Frequency Radar suffers electromagnetic interferences severely in wave band,thus a new waveform which is co-modulated by complementary P4 Phase-coded signal and by Quasi-Random Frequency Hopping signal is proposed.
针对高频雷达工作频段内电磁干扰严重的特点,本文利用准随机跳频原理与一种新的互补多相码设计出脉内互补 P4码调相脉间准随机跳频雷达信号,根据各脉冲间调相码组互补的特点研究出相应的距离信息和速度信息提取方法,仿真设计了满足实际系统性能指标的脉内互补 P4码调相脉间准随机跳频信号,提取了目标距离、速度信息,仿真结果证明该信号和传统高频雷达信号相比具有多普勒容限更大,分辨率更高, 抗干扰能力更强的优点。
