Modeling the Role of CSAR Team Based on AML
2012 International Conference on Machine Learning and Cybernetics, 2012How to plan the mission role of the CSAR (Combat Search and Rescue) assets is the key point of command control of the CSAR mission in modern and future military operations. In this paper, we analyze the necessary role type based on the requirements of the CSAR mission; and then model the role of the CSAR assets by means the agent diagram of AML (Agent ...

CSAR Surface as a Radiation Scatterer
2016 3rd International Conference on Electronic Design (ICED), 2016This research paper utilizes a 3D tetrahedral meshing frequency solver to simulate the electromagnetic effect of circular split asymmetric ring (CSAR) patterned onto a conventional microwave laminate. Behavior of the incident wave was first conducted using a bare flat metal laminate and then compared with a modified tip of CSAR surface. Comparison made

Extension of Polar Format Algorithm to CSAR Imaging for Arbitrary Region of Interest
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019We propose a fast algorithm to circular synthetic aperture radar (CSAR) imaging for arbitrary region of interest (ROI). This algorithm is an extension of traditional CSAR polar format algorithm (PFA). Firstly, to avoid severe defocus and distortion of off-centered ROI image caused by traditional CSAR PFA plane-wave approximation error, a novel PFA ...

A CSAR 3D Imaging Method Suitable for Edge Computation
Electronics, 2023 Due to the large amount of CSAR echo data carried by UAVs, either the original echo data need to be transmitted to the ground for processing or post-processing must be implemented after the flight.

A Method of Subaperture Division in CSAR Imaging
2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021This paper proposes an imaging algorithm with adaptive aperture energy division. This method is suitable for circular synthetic aperture radar (CSAR). The algorithm is an extension of the traditional CSAR polar format algorithm (PFA). Firstly, to avoid the loss of image detail information caused by the mismatch between the aperture size and the energy ...

Cryogenic Solar Absolute Radiometer (CSAR)
Metrologia, 1993The Cryogenic Solar Absolute Radiometer (CSAR) is a new primary radiometric standard for use in space traceable to the International. System of Units (SI). CSAR will have the potential to measure the total irradiance of the Sun with an uncertainty of 0.01% and a resolution of 0.001%, more than a factor ten improvement over existing instruments.

Fourier analysis based focusing of synthetic aperture radar (SAR) data collected during circular flight path is a recent advancement in SAR signal processing. Fast CSAR algorithm uses the Householder transform to obtain a ground plane circular SAR (CSAR) signal phase history from the slant plane CSAR phase history by inverting the linear shift ...

comparison of CSAR, E-CSAR and planar circular array for 3-d imaging
IET International Radar Conference 2015, 2015In this paper, three different three-dimensional imaging modes, i.e., Circular Synthetic Aperture Radar (CSAR), Elevation-CSAR (E-CSAR) and Planar Circular Array, are investigated in order to compare their 3-D imaging capability in terms of spatial resolution, spectral efficiency and the region of support in the wavenumber domain. The signal spectra of

In this chapter we introduce our communication-centric, scan-based, abstraction-based, run/stop-based (CSAR) debug approach and its associated infrastructure. This approach and its infrastructure meets the post-silicon debug requirements, identified in Chap. 1, and reduces the effects of the complicating factors for debugging, identified in Chaps.
