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.

A Primer on Zeroth-Order Optimization in Signal Processing and Machine Learning: Principals, Recent Advances, and Applications [PDF]

IEEE Signal Processing Magazine, 2020
Zeroth-order (ZO) optimization is a subset of gradient-free optimization that emerges in many signal processing and machine learning (ML) applications. It is used for solving optimization problems similarly to gradient-based methods. However, it does not

Digital Signal Processing Over Analog Signal Processing

Journal of Advance Research in Electrical & Electronics Engineering (ISSN: 2208-2395), 2014
This paper provides a survey of digital signal processing over analog signal processing. Initially digital signal processing is developed to replace limited application based analog signal processing (ASP) of high cost. This paper describes the comparison of analog signal processing (ASP) and digital signal processing, technology under digital signal ...
