TL;DR: Transmit pulsing schemes involving waveform diversity is proposed for improved target detection capabilities due to range foldover effects associated with multiple data points originating from different range bins and Earth's rotational effect on clutter Doppler frequency.
Abstract: Two phenomena that degrade the performance of ground moving target detection (GMTI) capabilities of space based radars (SBR) are (i) range foldover effects associated with multiple data points originating from different range bins due to the radar pulse stream and (ii) Earth's rotational effect on clutter Doppler frequency. The degradation in performance due to these phenomena is quantified in this paper and methods to minimize their effect are discussed. In this context, transmit pulsing schemes involving waveform diversity is proposed for improved target detection capabilities

TL;DR: This paper discusses methods that are suitable for assessing the performance of target tracking algorithms and emphasis is placed on applications involving ground moving targets detected by radar sensors, which are deployed on aerial platforms.
Abstract: This paper discusses methods that are suitable for assessing the performance of target tracking algorithms. Emphasis is placed on applications involving ground moving targets detected by radar sensors, which are deployed on aerial platforms. Numerical examples are provided in relationship with an experimental ground moving target indicator (GMTI) tracker available at NC3A.

TL;DR: Some Bayesian filtering algorithms are investigated and the Cram´er-Rao bounds based on subsets of radar measurements (range, angle and Doppler) are derived for typical maneuvering targets and compared against simulated results from Bayesian filters.
Abstract: In certain operational radar modes, slow ground moving targets are detected over several processing intervals
using space-time adaptive processing. This enables use of Bayesian filtering and smoothing algorithms for
estimation of time-varying moving target parameters. In this paper, some Bayesian filtering algorithms are
investigated. The Cram´er-Rao bounds based on subsets of radar measurements (range, angle and Doppler)
are derived for typical maneuvering targets and compared against simulated results from Bayesian filters. The
performance is also evaluated using real data obtained from DRDC Ottawa's XWEAR radar.

TL;DR: A novel method for ground moving target detection and imaging using a SAR system transmitting ultra-narrowband continuous waveforms and a new forward model that relates the velocity as well as reflectivity information at each location to a correlated received signal is presented.
Abstract: We present a novel method for ground moving target detection and imaging using a SAR system transmitting
ultra-narrowband continuous waveforms. We develop a new forward model that relates the velocity as well as
reflectivity information at each location to a correlated received signal. We reconstruct moving target images
by a filtered-backprojection method. We use the image contrast as a metric to detect moving targets and
to determine their velocities. The method results in well-focused reflectivity images of moving targets and
their velocity estimates regardless of the target location, speed, and velocity direction. We present numerical
experiments to verify our method.

TL;DR: This paper is dedicated to the preliminary analysis of the utilisation of an ultra wideband signal in forward scattering radar (FSR) for air target detection and some advantages of the wide spectrum ranging signal use are shown.
Abstract: This paper is dedicated to the preliminary analysis of the utilisation of an ultra wideband (UWB) signal in forward scattering radar (FSR) for air target detection. Some advantages of the wide spectrum ranging signal use are shown: ground clutter reduction, target resolution, altitude and direct target position evaluation.
