Joint High-Resolution Range and DOA Estimation via MUSIC Method Based on Virtual Two-Dimensional Spatial Smoothing for OFDM Radar by Rui Zhang, Ying-Hui Quan, Sheng-Qi Zhu, Lei Yang, Ya-chao Li, Meng-Dao Xing

“…It begins with the design and analysis of an echo model of OFDM array radar. Since there is no coupling between range and angle parameter estimation for a narrow-band signal, a method which exploits the data of one snapshot to estimate the range and angle of the target by means of multiple signal classification (MUSIC) based on virtual two-dimensional spatial smoothing in range and angle dimensions is devised. …”

Height measurement method of monostatic metre wave multiple input multiple output radar based on coprime array by Hongzhen Wang, Guimei Zheng, Yuwei Song

“…The proposed method calculates the echo data according to the characteristics of the steering vector of CPA, then obtains the accurate low elevation by using the generalised multiple signal classification algorithm, and finally the target height is obtained by using the geometric relationship. …”

Using WSR-88D Polarimetric Data to Identify Bird-Contaminated Doppler Velocities by Yuan Jiang, Qin Xu, Pengfei Zhang, Kang Nai, Liping Liu

“…In the first step, the fuzzy-logic method in the HCA is simplified and used to identify biological echoes (mainly from birds and insects). In the second step, another simple fuzzy logic method is developed to detect bird echoes among the biological echoes identified in the first step and thus remove bird-contaminated velocities. …”

The inner reformation of the sciences: an ambiguity in the radically orthodox thought of John Milbank? by D. F. M. Strauss

“…An alternative idea of Christian scholarship is advanced in opposition to Milbank’s classical Thomistic view, namely that theology has to preserve and fulfil philosophy, echoing the Scholastic adage that grace does not eliminate nature, but perfects it (gratia naturam non tollit, sed perficit). …”
