However, due to the inherent feathers of VHF, this type of radar is too subject to jammers to work well.

然而，由于米波固有的特点，米波雷达极易受到干扰而无法正常工作，因此提高米波雷达抗干扰的性能就成为SIAR研究中的一个重点内容。

Traditionally, jammers have operated by determining the operating frequency of the radar and then broadcasting a signal on it to confuse the receiver as to which is the "real" pulse and which is the jammer's.

传统上，阻塞器用雷达的操作频率来进行，广播一个信号到雷达以使之不能分清哪个是&真的&脉冲哪个是阻塞信号。

The return signal from propeller aircraft and jet plane in different SNR is simulated based on the statistic model of the disturbed clutter,a...

根据给定的目标建模算法和干扰反射杂波模型，模拟了不同信杂比下螺旋桨飞机和喷气式飞机的雷达回波，仿真结果表明，这两种目标具有不同的频谱结构，证明了给出的模型是有效的，为雷达系统提供了实用的回波仿真信号。

The return signal from propeller aircraft and jet plane in different SNR is simulated based on the statistic model of the disturbed clutter, and the calculated results are analyzed and compared. The results show that the model presented is valid and provides a useful simulated signal for the radar system.

根据给定的目标建模算法和干扰反射杂波模型，模拟了不同信杂比下螺旋桨飞机和喷气式飞机的雷达回波，仿真结果表明，这两种目标具有不同的频谱结构，证明了给出的模型是有效的，为雷达系统提供了实用的回波仿真信号。

The performance of radar's klystron affects directly the quality of radar echoes and operating cost, so the proper use and maintenance of klystrons are paid increasing attention presently.

雷达速调管的性能直接影响到雷达探测的回波质量及操作成本，因此速调管的使用维护也日益受到人们的重视。

Radar experts have referred to SCR-584 as "the most widely used and generally successful of the resulting equipments" from the application of magnetrons to ground-based radars.

雷达专家们称它是磁控管技术在陆基雷达应用上&最多用途和成功的装备&。

In 1945 Percy Lebaron Spencer, an American engineer and inventor, was busy working on manufacturing magnetrons , the devices used to produce the microwave radio signals that were integral to early radar use.

1945年，美国工程师与发明家斯宾塞正忙着制造磁控管，这种装置能发出早期使用雷达所必需的雷达微波信号。

I will endeavour to find you some assistance.

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
