We consider the data-driven motion compensation problem in inverse synthetic aperture radar (ISAR) imaging. We present optimization-based ISAR techniques and propose improvements to the range alignment, time-window selection, autofocus, time–freque

In this paper, we consider estimating the distribution of the radar cross section (RCS) using a small number of sparse measured samples. With a small sample size, it is advantageous to use the measured samples in combination with a preliminary descri

Applications such as radar performance prediction and automatic target recognition (ATR) require a compact description of the target and the ability to simulate target signatures fast. The complexity of the target model often slows the estimation of

The optimal use of a surveillance radar system requires proper understanding about the system behavior in different configurations, modes, and operating conditions. This paper proposes a machine learning framework for producing and validating the per

The objective of the radar performance prediction is to compute quantities of interest concerning the ability of the radar to observe its surroundings. Besides the properties of the radar system, the performance is affected by the target, whose radar

In this paper, we propose data-driven optimization techniques for enhancing the ISAR image reconstruction process. We utilize keystone formatting to compensate for the range cell migration caused by the rotational motion and the well-established tech

The traditional approach to inverse synthetic aperture radar translational motion compensation is to solve the problem in the two distinct parts of range alignment and autofocus. In this paper, we follow this practice and propose an approach based on

In the modern radar target recognition, the model-based approach offers a flexible and computationally efficient way to characterize targets, since establishing an adequate target signature collection especially with bistatic measurements is impracti

The radar cross section (RCS) of a target describes its reflectivity towards the radar. It is a deterministic quantity—specific to the aspect angle of the target and the properties of the radar signal—and as such can be predicted with various met
