ABSTRACT Three-axis flying posture simulator is a set of precise and sophisticated equipment with important significance of economy and national defence. TFPS is a kind of powerful instrument used to reproduce the flying posture of flying weapons in laboratory. TFPS, together with equipment producing infrared target, simulates the attacked target and flying missile, which can really simulate the various flying postures in space and dynamic characteristics. Thus, the performances of sensors, control system and actuator and so on can be tested and evaluated, which provides various reference bases for developing, improving and redesigning flying weapons.

三轴飞行姿态仿真转台是具有重大经济价值和国防战略意义的高精尖试验设备，它是在实验室条件下复现飞行器或导弹在空中飞行姿态的有力工具，它和红外目标发生装置组合在一起模拟袭击目标和飞行导弹，可以真实地模拟出导弹等飞行器在空间的各种姿态和动力学特性，从而对其传感器件、控制系统和执行机构等硬件设备的性能加以测试和评价，为飞行器的研制、改进和再设计提供各种参考依据。

To develop Linear Fractional Transformation model based on quasi-linear model for ground-to-air missile, state transformation method was used to establish quasi-Linear Parameter Varying model for missile longitudinal short-period dynamics by changing missile states along with an equilibrium trajectory decided by time-varying parameters. Based on the obtained quasi-LPV model, the LFT model of the missile was developed by use of MATLAB functions, and the missile dynamics were explicitly separated into certainty part and time-varying parameter part.

为了建立基于准线性化模型的地空导弹线性分式变换模型，采用状态替换方法将导弹的状态沿着一条由时变参数决定的平衡点轨迹进行变换，建立了纵向短周期动力学的准线性参数时变模型；基于所建立的准LPV模型，采用MATLAB函数建立了导弹的LFT模型，将导弹动力学明确描述为确定性部分和时变参数部分。

Authorities are looking for three types of manpads, or man-portable air-defense systems, including SA-7s and stingers, the officials said

这些官员说，当局正在搜寻3种型号的肩扛式防空导弹，其中包括SA－7地对空导弹和"毒刺"式防空导弹。

The effect of change in physical and chemical environment caused by firing the man-portable anti-tank missiles from narrow space,typically civilian buildings,on the living being was analyzed by the experiment.

系统分析了反坦克导弹室内射击的特点、可能对射手造成的损伤，通过试验重点分析便携式反坦克导弹在以房舍为代表的狭小空间内射击时物理和化学环境变化对生物的影响，为便携式反坦克导弹适应房舍等狭小工事内射击的设计和使用提供参考依据。

To develop the missile quasi-linear model, a state space model is established for missile dynamics, and function substitution method is used to describe the nonlinear dynamics of missile as linear combinations of functions of given time-varying parameters. With the minimizing variation range of model parameters over the whole design envelope as the optimum aim, linear programming optimum arithmetic is used to determine the model parameters at selected grid points.

为了建立导弹准线性化模型，将导弹动力学描述为状态空间形式；采用函数替换方法将导弹的非线性动力学描述为关于特定时变参数的函数的线性组合形式；以整个设计区间内模型参数变化范围最小为优化目标，采用线性规划优化算法确定了所选网格点上的模型参数。

Meanwhile, we proposed the signal data overflow handling algorithm to deal with the possible missile target missing caused by the infrared interference, and the infrared signal flicker because of the infrared attenuation in atmosphere.

简要介绍了反坦克导弹红外测角仪的信息处理系统组成原理，讨论了红外测角仪抗红外干扰的信息处理方法，导弹目标信号的确定要通过真假红外信号的模式识别和航迹判别处理等才能最终确定，同时对由于大气红外衰减造成的红外信号闪烁以及其它干扰造成的导弹目标丢失情况，设计了信号数据溢出处理模块。

2006年3月5日在大西洋游戈的航母舰队：核动力航空母舰艾森豪威尔号CVN-69、伯克级导弹驱逐舰梅森号USS Mason DDG-87、伯克级导弹驱逐舰雷米吉号USS Ramage DDG-61、提康德罗加级导弹巡洋舰安齐奥号USS Anzio CG-68。

To this end the original 'Blue Fox' radar is replaced by Ferranti 'Blue Vixen' coherent pulse-Doppler track-while-scan radar to improve acquisition and look-down capabilities, and other improvements are a MIL 1553B digital databus (making it possible to carry Sea Eagle anti-ship and ALARM anti-radar missiles) and the installation of the Marconi Sky Guardian 200 RWR, the JTIDS for secure voice and data links, two additional underwing hardpoints, wing tip stations for two AIM-9 Sidewinder short-range AAMs, wing improvements, a revised cockpit with HOTAS controls, larger drop tanks, provision for 25 mm Aden 25 cannon in place of the elderly 30 mm weapons, and possibly a Plessey missile-approach warning system.

为实现这一目的，原有的"蓝狐"雷达被新型的"蓝雌狐"连续波脉冲多普勒雷达替换，该雷达具有搜索的同时锁定目标的能力，可下视下射。其他改进包括加装军用1553B数据链，这使得MK2可以使用"海鹰"反舰导弹和ALARM反雷达导弹。另外加装了马可尼"天空哨兵200"通信系统，JTIDS保密语音及数据链路。增加了两个翼下外挂点，翼尖挂架可携带两枚AIM-9"响尾蛇"近距空空导弹。细节的改进还包括：机翼设计有所改进；改进的座舱设计；更大的副油箱；采用阿登25mm机关炮代替了以往的30mm机炮；可能加装了导弹告警系统。

The AGM-88 is a second-generation air-to-ground antiradiation missile. The F-16 can currently carry two HARMs, though four-HARM loads are being flight-tested at Eglin AFB.

AGM-88是第二代空对地反辐射导弹。F-16一般情况下可以携带两枚HARM导弹，尽管在伊格林空军基地通过了携带四枚HARM导弹的外挂飞行测试。

It also improved the radar, expanded the fire control and stores control computers, allowed Block 15 aircraft to fire the AGM-119 Penguin antishipping missile, the AGM-65 Maverick air-to-ground missile, and the AIM-120 advanced medium-range air-to-air missile, or AMRAAM.

它还改进了雷达，扩展了火控和外挂控制计算机，允许第15批次的飞机发射AGM-119'企鹅'反舰导弹，AGM-65'小牛'空对地导弹，还有AIM-120先进中距空对空导弹，也就是AMRAAM。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
