A Wideband digital Beamforming Method Based on Stretch Processing
نویسندگان
چکیده
The calculation of wideband digital beamforming using traditonal methods is so large that it is hard to realize in project. This paper describes a wideband digital beamforming method on the base of stretch processing for linear frequency modulated (LFM) waveforms. This method offers advantages that are moderate data rate for wideband signal processing by reducing the signal bandwidth greatly. In addition, the method not only can get high range resolution of wideband array radar, but also can form good shape pattern with null at interference, as the simulation results show. To the most important, this method compared to traditional methods is easier for engineering implementation greatly. Key-Words: Digital beamforming (DBF), linear frequency modulated (LFM), Stretch Processing , wideband, Digital array radar

TDL-based Wideband Beamforming for Radio Sources Close to the Array Endfire
Uniform linear array (ULA)-based tapped-delay line (TDL) structure has good performance metrics when the signal sources are located at the middle angles. It offers poor performance when the signal sources are close to the array endfire. In this paper, a new approach is proposed which offers higher performance and desired beamforming on TDL structure when the wideband uncorrelated radio sources ...

In this paper, a new approach for estimating the number of wideband sources is proposed which is based on RSS or ISM algorithms. Numerical results show that the MDL-based and EIT-based proposed algorithm havea much better detection performance than that in EGM and AIC cases for small differences between the incident angles of sources. In addition, for similar conditions, RSS algorithm offers hi...

متن کاملA Non-linear Algorithm for Digital Beamforming of a Wideband Active Sonar Array
A signal interpolation technique based on the Hilbert transform of a signal is proposed. This technique can be efficiently used for fractional time delay estimation. A useful application of the technique is demonstrated using examples of digital beamforming with wideband signals. Conventional wideband signal beamforming is computationally intensive due to the calculation of fractional time dela...
