噪声是客观存在的.对有用信号构成干扰和威胁的噪声,是限制接收系统获得最大灵敏度的主要障碍,设法减少噪声极为重要.为消除外部噪声(如人为噪声),必须严格执行有关噪声的环境保护和频率管理法规,采用高稳定度的频率源和优质电子器件,对高频设备加强屏蔽和电源滤波等；为消除内部噪声,常采用工作在非常低的温度条件下的其他类型低噪声放大器作为接收系统的第一级放大,或采用减小馈线损耗等办法.外部噪声数据是无线电系统的重要环境参数.

Noise exists objectively. The noise which disturbs and threatens useful signals is the main obstacle to the receiving system to reach the maximum sensitivities, trying to reduce noises is extremely important. In order to diminish the external noise (e.g. man-made noise), rules which are related to the noisy environment protection and frequency limitation must be carried out strictly, using highly stable frequency and high quality electrical apparatus, or enhance the shielding and electrical source filtration of the high frequency apparatus; In order to diminish the internal noise, usually a low noise magnifying machine which can work at low temperatures is used as the first magnifier of the receiving system, or reduce the consumption of the feeder line. External noise data is a important environmental parameter of the wireless system.

The noise is the objective existence. Constitutes the noise which to the wanted signal disturbs and threatens, is limits the receiving system to obtain the greatest sensitivity the chief obstacle, tries to reduce the noise great importance. In order to eliminate the external noise (for example man-made noise), must fulfil exactly the related noise environmental protection and the frequency management regulation, uses the high stability the frequency source and the high quality electronic device, strengthens the shield and the power source filter to the high frequency equipment and so on; In order to eliminate the internal noise, often uses the work to enlarge under very low temperature condition other type low noise amplifier as the receiving system's first level, or uses reduces means and so on feed line loss. The external noise data is the radio system's important environment parameter.

Noise is an objective fact. Of a useful signal interference and the threat of noise, the receiving system is to limit the maximum sensitivity of the major obstacles to try to reduce the noise is extremely important. To eliminate external noise (such as artificial noise), we must strictly enforce the noise and frequency of environmental protection laws and regulations governing the use of high-stability frequency source and quality of electronic devices, equipment to strengthen the high-frequency power supply filtering and shielding; to eliminate internal noise , and often work in a very low temperature under the condition of other types of low-noise amplifier, as the first level of the receiving system to enlarge or reduce feeder loss by such means. External noise data radio system is an important environmental parameters.
