On angular resolution in microwave radar
Proceedings of the IEEE, 1974The large dynamic range required to obtain stable microwave images causes angular resolution to be a function of the sidelobe level. It is particularly significant in synthetic aperture radar. It is shown that a modest tapering of the synthetic aperture offers a dramatic potential improvement.

On the Accuracy And Resolution of Radar Signals
IEEE Transactions on Aerospace and Electronic Systems, 1965Information matrices are derived for estimates of the range parameters of moving targets as obtained by combining a priori information (if available) with reflected radar signals observed in the presence of additive white Gaussian noise. The inverse of the information matrix provides a lower bound on the covariance matrix of any unbiased parameter ...

1988
Abstract : The goal of this project is to formulate and investigate new approaches for forming images of radar targets from spotlight-mode, delay- doppler measurements. These measurements could be acquired with a high- resolution radar-imaging system operating with an optical- or radio-frequency carrier. Two approaches are under study.

Fine Resolution of Radar Targets
1994In this chapter, we present an overview, aided by a systematic progression of concrete examples, of the mathematical and especially the physical details which enter into a description of the radar target scattering process. Mathematically, the singularity expansion method (SEM) is a powerful approach to the calculation and understanding of radar ...

On the optimum range resolution of radar signals in noise
IEEE Transactions on Information Theory, 1961Optimum radar resolution is recognized to be a problem in distinguishing between different possible target configurations. Radar reception systems which perform optimum range resolution are then designed using the principles of statistical decision theory.

Maximum likelihood postdetection radar ambiguity resolution
IEEE Transactions on Aerospace and Electronic Systems, 2014Doppler and range ambiguity are common problems in radar systems. In this paper, a maximum-likelihood estimator taking advantage of the circular nature of the data is proposed and, using an example of detection using multiple digital television channels, is shown in all but instances of high noise to perform comparably to a popular clustering algorithm

The resolution capabilities in inverse synthetic aperture radar
1989The resolution attainable by an Inverse Synthetic Aperture Radar system is discussed. The image reconstruction method is based on recovering the target reflectivity function by an inverse Fourier transform of the received signal samples collected for different positions of radar and target.
