    Abstract: The invention relates to a method for beam formation by calculation. For each defective active module of rank ip, the missing samples of the microwave signal a(îp) are calculated by one or more non-adaptive interpolations using the samples coming from the active modules in nominal operating mode situated in the neighborhood of the defective active modules, the beam being formed as if the interpolated samples a(îp) were the real measurements. In particular, the invention is applicable to the compensation for the effects of failures of one or more active modules distributed over an antenna of a radar with electronic scanning. The method according to the invention can notably be implemented within an airborne weather radar.

    Abstract: An aim of the invention is to allow the detection of turbulence in the absence of tracers. A radar is embedded aboard an aircraft (21) and implements the following steps: searching for the upper part of a convective system (1) situated outside the given zone, reflecting the electromagnetic waves; searching for divergence zone (7) inside the convective system by searching for a divergence profile; reckoning the appearance of turbulence in the given zone as a function of observable meteorological phenomena in the divergence zone (7) by applying fluid mechanics properties.

    Abstract: Disclosed is a device for the reduction of noise in a radar receiver. The noise to be reduced being governed by a 1/F.sup.k relationship and the radar carrying out an encoding of the transmission in at least two frequencies, the device comprises at least the following means: firstly, means for routing the signals received to at least two channels so that, when a target is illuminated by a transmission at the first code frequency (F.sub.1), the corresponding received signal (S.sub.1) is sampled and routed to a first channel and then, when the target is illuminated by the second code frequency (F.sub.2), the corresponding received signal (S.sub.2) is sampled and routed to a second channel; and secondly, means for the linear combination of the signal (S.sub.1) present in the first channel and the signal (S.sub.2) present in the second channel, the linear combination synthesizing a filtering of the noise.
