WebClutter suppression for airborne non-sidelooking radar is a challenging problem due to the range-dependent clutter. In this study, an algorithm combining elevation robust Capon beamforming (ERCB) and two-dimensional azimuth-Doppler space–time adaptive processing (STAP) is presented to realise clutter suppression for airborne non … Web文献[6]稳健算法首先利用期望信号来向区间及Capon功率谱重构干扰噪声协方差矩阵,然后通过迭代搜索的方法求解二次凸优化问题获得修正的期望信号导向矢量。文献[13]给出了一种联合稳健算法,首先利用Shrinkage方法增强协方差矩阵的稳定性,然后结合文献[10]中的 ...

http://acoular.org/api_ref/generated/generated/acoular.fbeamform.BeamformerCapon.html Beamforming or spatial filtering is a signal processing technique used in sensor arrays for directional signal transmission or reception. This is achieved by combining elements in an antenna array in such a way that signals at particular angles experience constructive interference while others experience … See more To change the directionality of the array when transmitting, a beamformer controls the phase and relative amplitude of the signal at each transmitter, in order to create a pattern of constructive and destructive … See more The delay-and-sum beamforming technique uses multiple microphones to localize sound sources. One disadvantage of this technique is that adjustments of the position or of the … See more To receive (but not transmit ), there is a distinction between analog and digital beamforming. For example, if there are 100 sensor elements, the "digital beamforming" … See more Sonar beamforming utilizes a similar technique to electromagnetic beamforming, but varies considerably in implementation … See more • A conventional beamformer can be a simple beamformer also known as delay-and-sum beamformer. All the weights of the antenna … See more Beamforming techniques used in cellular phone standards have advanced through the generations to make use of more complex systems to … See more Beamforming can be used to try to extract sound sources in a room, such as multiple speakers in the cocktail party problem. This requires the locations of the speakers to be known in … See more generation cordless iron

WebAbstract: In this paper we present a 60-GHz radar material classification system based on a Deep Convolutional Neural Network (DCNN), which uses images from the radar sensor as input features. These so called range cross-range images are generated with a Capon beamforming algorithm. WebJan 8, 2024 · The X-band phased-array weather radar (PAWR) operated by the Osaka University, performs a full-volume scan every 30 s within a 60-km range. For the waves … WebMay 31, 2013 · This paper proposes an approach to suppress clutter in the context of CS MIMO radars.
