FH Spread Spectrum System simulation in MATLAB

说明：   该电路由一片四双向模拟开关集成电路CD4066为核心构成。每个电路内部有四个独立的能控制数字或模拟信号传送的开关。当水箱无水时，由于180K电阻的作用，使四个开关的控制端为低电平，开关断开，LED 不发光。随着水位的增加, 由于水的导电特性，使得IC的13脚为高电平，S1接通，LED1点亮。当水位逐渐增加时，LED依次发光指示水位。水满时， LED4发光， 显示水满。同时T1导通， B发出报警声，提示水已满。不需要报警声时，断开开关K即可。 (The circuit consists of a four-way analog switch integrated circuit CD4066 core composition. Within each circuit to control four separate digital or analog signal transmission in the switch. When the tank water, the role of the 180K resistor, so that the four low-side switch control, switch off, LED does not light. As the water level increases, the electrical properties of water, making the IC' s 13 feet high, S1 connected to, LED1 lights up. When the water level gradually increased, LED turn light level indication. Is full of water, LED4 LED display full of water. At the same time conducting T1, B alarm will sound, indicating that the water is full. Do not need to sound the alarm when the disconnect switch K can be.)

说明：  求误差函数的值（算法借鉴MATLAB中erf函数）(According the erf function in matlab program, get the value of ERROR function.)

雷达系统设计 恒虚警处理 MTI、MTD(radar system design)

转资料，四旋翼飞行器的自适应控制仿真，用的是别人做好的算法，自己已经编好S函数和搭建好模型(Transfer information, four rotor aircraft adaptive control simulation, the best algorithm with others, you have good S function and set up good model)

说明：  模拟智能仓储机器人移动，有效进行路径规划避碰(simulation of intelligent warehousing robot)

在hfss中matlab编程，实现合并操作(In hfss in matlab programming, to achieve the combined operation)

说明：  多目标跟踪的matlab代码，其中背景差分法可以实现实时更新。该代码在检测与跟踪少量目标时效果很好,但是跟踪目标大于8后,效果下降很多。(Multi-target tracking matlab code)
