摘要： In the field of the radar monitoring of airspace zones, and more particularly to the low altitude air surveillance of zones that are more or less densely populated with fixed objects comprising moving parts, such as wind turbines for example, two processing modules are applied to the raw signal Sb(t) received by the radar. The first module carries out the recognition in the signal Sb(t) of a signal reflected by a wind turbine, the recognition being performed by detecting an evolution in the course of time of the amplitude of the signal received Sb(t), characteristic of this type of signal. The first module also formulates a spurious-signal model either directly on the basis of the signal Sb(t) or on the basis of external real-time information relating to the operating state of the wind turbine whose signal has been detected. The second module executes the filtering proper of the signal Sb(t), this filtering consisting in subtracting the spurious-signal model s(t) from the signal Sb(t). The filtered signal Sf(t) is transmitted to the processing operating downstream of the method according to the invention.
摘要翻译：在空域区域的雷达监测领域，更具体地说，涉及到或多或少地密集地安装有诸如风力涡轮机等运动部件的固定物体的区域的低空空中监视，将两个处理模块应用于由雷达接收的原始信号Sb（t）。第一模块在风力涡轮机反射的信号的信号Sb（t）中进行识别，通过检测接收到的信号的振幅的时间过程Sb（t）来进行识别，进行识别，其特征在于这种信号。第一模块还直接基于信号Sb（t）或基于已经检测到信号的风力涡轮机的运行状态的外部实时信息来制定寄生信号模型。第二模块执行信号Sb（t）的滤波，该滤波包括从信号Sb（t）中减去寄生信号模型s（t）。滤波后的信号Sf（t）被发送到根据本发明的方法的下游操作。

摘要： Coaxial filter having at least one of the internal and external conductors which is divided into sections (S.sub.1 to S.sub.4) separated by breaks having to form of annular slits whose thickness is very slight in relation to the wavelength.Each section comprises at least one reactive tuning element such as an open or short-circuited coaxial line portion and at least one switch element located in the vicinity of the corresponding break in order selectivity to short-circuit the said break or bring about the insertion of the corresponding reactive tuning element in response to electronic control devices.Application to telecommuncations.
