DVB-T Passive Radar Signal Processing
IEEE Transactions on Signal Processing, 2013This paper provides a detailed overview of the Digital Video Broadcasting Terrestrial (DVB-T) signal structure and the implications for passive radar systems that use these signals as illuminators of opportunity. In particular, we analyze the ambiguity function and explain its delay and Doppler properties in terms of the underlying structure of the DVB-

IEEE ASSP Magazine, 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 ...

Signal Processing for Space Surveillance Radar
2022Space Situational Awareness (SSA) by ground-based Digital-Array Radar (DAR) systems has been attracting global attention in recent years. One of its fundamental tasks is to provide accurate collision forecast between space debris and active satellites, leading to increased avoidance probability.

Multistatic Radar Systems Signal Processing
2006 IEEE Conference on Radar, 2006In this paper, a multistatic radar system with multiple receivers and one transmitter is analyzed. We address the rules for selecting the weights for fusing multiple receivers in order to meet pre-specified performance goals. A multistatic radar ambiguity function is used to relate different radar performance measures to system parameters such as radar

Frequency-Agile Radar Signal Processing
IEEE Transactions on Aerospace and Electronic Systems, 1979Modern radars may incorporate pulse-to-pulse carrier frequency modulation to increase probability of detection, to reduce Vulnerability to jamming, and to reduce probability of interception. However, if coherent processing is used for clutter rejection, the frequency of N consecutive pulses must be held constant for N-pulse clutter cancellation or ...

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.

Meteorological Radar Signal Processing
1978Modern meteorological Doppler radar has applications related to measurements of precipitation intensities and kinematics in convective storms, widespread stratiform precipitating systems, winter frontal and cyclonic storm systems, and other cloud systems. In addition, air velocities may be measured in the optically clear atmosphere from backscatter due

Stepped-frequency radar signal processing
Journal of Applied Geophysics, 2015Abstract Stepped-frequency radar is a prominent example of the class of continuous-wave radar systems. Since raw data are recorded in frequency-domain direct investigations referring to the frequency content can be done on the raw data. However, a transformation of these data is required in order to obtain a time-domain representation of the targets ...

Publisher Summary This chapter explores that, considerable progress has been made in radar signal processing. This progress is directly traceable to the lowered cost and increased speed of digital hardware and computers and to more sophisticated techniques in the areas of adaptive processing and tracking systems.
