Radar resolution of moving targets
IEEE Transactions on Information Theory, 1967Conventional resolution theory is based on the assumption of constant range rate, and it neglects distortions of the modulation function as well as effects of the antenna pattern. Among the generalizations of the theory reported in the literature, some include the antenna pattern and others retain higher-order range derivatives in both carrier term and

Proceedings of the IRE, 1951
The problem of azimuthal resolution in radar systems is discussed. It is shown how the resolution is related to the antenna beamwidth and thus in turn to the size of aperture. The possibilities of improving resolution beyond the normal capabilities is considered and the limitations are presented from two aspects.

Generalized Resolution in Radar Systems
Proceedings of the IRE, 1962A generalized theory of radar resolution has been developed to facilitate understanding of the fundamental resolution limitations of radar systems. Previous work by Woodward and Elspas to determine limitations on radar resolution led to the concept of an ambiguity function which is a quantitative measure of radar resolution in range and range rate ...

High-resolution instrumentation radar
IEEE Transactions on Instrumentation and Measurement, 1987An instrumentation radar that uses a chirp waveform to achieve high-range resolution is described. High-range-resolution instrumentation radars evaluate the target response to operational waveforms used in high-performance radars and/or obtain display of the individual target scattering mechanisms to letter understand the scattering process.

Detection for high resolution radars
Journal of the Chinese Institute of Engineers, 1998Abstract In this paper we discuss detection problems for a high resolution radar. Fluctuation in the target radar cross section usually decreases the probability of detection. However, through integration of cells within range profiles of a high resolution radar, variation of the integrated magnitude with respect to the change of carrier frequency and ...

Fully Adaptive Radar for Variable Resolution Imaging
IEEE Transactions on Geoscience and Remote Sensing, 2019This paper describes the first application of the fully adaptive radar (FAR) framework for cognition to the process of radar imaging. A cognitive radar adapts to its surroundings based on its perceptions of the environment, offering improved performance for a multitude of radar applications.

RESOLUTION IN HEIGHT OF A RADAR PULSE
Journal of Meteorology, 1955Abstract The resolution in height of a radar pulse is of interest in connection with the observation and interpretation of horizontally stratified echoes, and also in the comparison of values of echo intensity measured at different ranges and elevation angles.

Sequential detection in radar with multiple resolution elements
IEEE Transactions on Information Theory, 1962In this paper the techniques of sequential analysis are applied to a multiple-resolution-element search radar for different types of detection. By using sequential methods such a radar shows considerable saving compared to fixed-scan-rate detection radars.

Ship classification with high range resolution radar
2018 26th Signal Processing and Communications Applications Conference (SIU), 2018In this study, the classification problem of the ships that near field of the radar is researched. For this classification process, two dimensional high resolution range profiles obtained from radar simulator are used. In this scope the features extracted from image data that obtained from radar near field and classification success of different ...
