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.

Signal processing for automotive radar
IEEE International Radar Conference, 2005., 2005With rising accident rates, researchers are looking for solutions to reduce fatalities. Some enhance car designs to protect drivers more adequately. Some propose improvements to the traffic and road systems to reduce the chances of accidents. Still others propose the installation of special gadgets to improve the situational awareness of drivers and to

Elementary Radar Signal Processing
2004Having examined how a radar signal is generated, is emitted from the antenna, scatters from external objects, reenters the radar, and is recorded as a voltage by an A/D converter, we now begin consideration of how to interpret the resulting measurement.
