Multi-Resolution STAP for Enhanced Ultra-Low-Altitude Target Detection
Remote Sensing, 2021 In this paper, an ultra-low-altitude target (ULAT) detection approach, referred to as the multi-resolution space-time adaptive processing (STAP), is proposed to enhance the target detection performance in a missile-borne radar system.

Nonlinear signal processing [PDF]
2005 IEEE LEOS Annual Meeting Conference Proceedings, 2005 This paper studies the propagation of femtosecond pulses in a Kerr medium both experimentally and numerically. This work also investigates the similarities between the propagation of light pulses in a Kerr medium and the evolution of fluid dynamical systems, and proposes the use of an optical system to simulate fluid dynamics.

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 ...

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada
Population Ecology, EarlyView.We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

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.
