Commercial off-the-shelf computer systems with reconfigurable architectures have recently become available. Some of these machines have architectures, features, and software development environments that seem to make them useful for digital signal processing, especially in electronic warfare and radar signal processing applications.This paper describes experiments to evaluate the architecture, ...

This paper analyzes noise reduction using matched filter and wavelet transform in the signals of continuous wave radar and pulse radar. The denoising application of wavelets has been used in spectrum cleaning of atmospheric radar signals. Matched filter has a strong anti-noise ability; it can also achieve accurate pulse compression in a very noisy environment. This paper analyzes the algorithms...

Radar systems, based on bistatic radar concept attracted a substantial attention in the recent years. Passive coherent location systems using “transmitters of opportunity” like radio or TV broadcasters, GSM base stations, satellite communication and GNSS signals proved their potential in detection and tracking moving targets over a significant area. In this paper the multistatic location system...

This paper considers the processing of radar signals in digital radar rangefinders. Special attention is focused on the case where limited performance of digital signal processors cannot provide the input signal sampling rate corresponding to the Nyquist criterion. The considered method of stroboscopic sampling allows overcoming this limitation. A suggested pseudo random modification of the str...

The proliferation of mobile computing devices and local-area wireless networks has fostered a growing interest in location-aware systems and services. In this paper we present RADAR, a radio-frequency (RF) based system for locating and tracking users inside buildings. RADAR operates by recording and processing signal strength information at multiple base stations positioned to provide overlappi...

The embedded ultrasonic structural radar (EUSR) algorithm was developed by using piezoelectric wafer active sensor (PWAS) array to detect defects within a large area of a thin-plate specimen. EUSR has been verified to be effective for detecting a single crack either at a broadside or at an offside position. In this research, advanced signal processing techniques were included to enhance inspect...

This application report introduces the DSS, discusses the key blocks of the DSS, provides benchmarks for the digital signal processor (DSP) and enhanced direct memory access (EDMA), and presents typical radar processing chains that are intended for engineers who wish to implement signal processing algorithms on the AWR16xx.

In future parallel radar signal processing systems, with high bandwidth demands, new interconnection technologies are needed. The same reasoning can be made for other signal processing applications, e.g., those involving multimedia. Fiber-optic networks are a promising alternative and a lot of work have been done. In this paper, a number of fiber-optic interconnection architectures are reviewed...
