IEEE ASSP Magazine (Acoustics, Speech, and Signal Processing), 1985
A review of recent developments in radar signal processing in the presence of clutter is presented, with particular reference to an air-traffic environment. Two different signal processing issues are considered. The first issue relates to the adaptive suppression of clutter (of unknown statistics) and consequent enhancement of the echo produced by a ...

The Doppler Radar Signals Processing
2019 9th International Conference on Advanced Computer Information Technologies (ACIT), 2019A spectral method for processing Doppler radar signals is proposed. Discrete fast Fourier transform is commonly used in communications (areas) in both mobile phone processes and devices for compressing audio and video to transmit via telecommunications networks. For now the relevant objective is to increase the efficiency of these systems.

Approaches to Radar Signal Processing
Computer, 1983The goal of modern radar signal processing is to improve the accuracy and dependability of detection and measurement in radar systems. In addition to the desired signals, radar systems receive interference and noise signals, many of which can be quite strong. The receiver and associated elements also generate noise.

Digital signal processing for doppler radar signals
ICASSP '79. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005In a pulsed-doppler radar system the return signal is naturally viewed as a sequence of samples of one or more complex sinusoids plus noise. We have studied several digital processing techniques for estimating a short-time spectral representation of such signals as well as digital techniques for estimating the frequency of a single dominant spectral ...

ISARLAB: a radar signal processing tool
Proceedings of ICASSP '94. IEEE International Conference on Acoustics, Speech and Signal Processing, 2002Collecting radar data in the field is both expensive and time consuming. The paper presents a radar simulator called ISARLAB which has been specifically designed to meet the needs of high resolution target classification studies. The main problem with radar simulation is modeling complexity.

The processing of HF skywave radar signals
Proceedings of ICASSP '94. IEEE International Conference on Acoustics, Speech and Signal Processing, 2002This paper presents an overview of a significant and computationally demanding application of signal processing, viz. over-the-horizon radar (OTHR). The Jindalee Operational Radar Network is an integrated network of OTHRs which depend heavily for their performance, in both air and surface mode, on signal processing.

Group delay processing of radar signals
ICASSP '86. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005A new method of processing the radar signals is presented in this paper. The method is based on the two properties of the magnitude group delay (MGD) function, namely, MGD has high resolution, and it is possible to manipulate different regions of the spectrum independently in the MGD domain.
