System Realization of Broad Band Digital Beam Forming for Digital Array Radar
Leida xuebao, 2013 Broad band Digital Beam Forming (DBF) is the key technique for the realization of Digital Array Radar (DAR). We propose the method of combination realization of the channel equalization and DBF time delay filter function by using adaptive Sample Matrix ...

Improved range model based on parameter estimation for high resolution and high squint LEO SAR
The Journal of Engineering, 2019 Due to the curve of the LEO synthetic aperture radar (SAR) orbit and the rotation of the earth, the high resolution imaging for LEO SAR is always facing the problem of obtaining accurate range history.

Wavelets and signal processing [PDF]
IEEE Signal Processing Magazine, 1991 A simple, nonrigorous, synthetic view of wavelet theory is presented for both review and tutorial purposes. The discussion includes nonstationary signal analysis, scale versus frequency, wavelet analysis and synthesis, scalograms, wavelet frames and orthonormal bases, the discrete-time case, and applications of wavelets in signal processing.

Topological Signal Processing over Simplicial Complexes [PDF]
, 2019 The goal of this paper is to establish the fundamental tools to analyze signals defined over a topological space, i.e. a set of points along with a set of neighborhood relations. This setup does not require the definition of a metric and then it is especially useful to deal with signals defined over non-metric spaces.
