Radar Cross-Section Measurements and Simulation of a Tethered Satellite. the Small Expendable Deployer System End-Mass Payload

Pages : 24
Book Description
The first Small Expendable Deployer System (SEDS-1), a tethered satellite system, was developed by NASA and launched March 29, 1993 as a secondary payload on a United State Air Force (USAF) Delta-2 launch vehicle. The SEDS-1 successfully deployed an instrumented end-mass payload (EMP) on a 20-km nonconducting tether from the second stage of the Delta 2. This paper describes the effort of NASA Langley Research Center's Antenna and Microwave Research Branch to provide assistance to the SEDS Investigators Working Group (IWG) in determining EMP dynamics by analyzing the mission radar skin track data. The radar cross section measurements taken and simulations done for this study are described and comparisons of the measured data with the simulated data for the EMP at 6 GHz are presented.

Book Description
Describes a time-based computer simulation of a space-based radar (SBR) system. The simulator models the orbital dynamics of multiple radar satellites and the characteristics of the radar, and computes the clutter returns from the surface of the earth as a function of Doppler velocity. It then determines the theoretical detectability of a target of specified radar cross-section, location, and velocity at any given time. The simulator is used to carry out studies of the detection performance of a generic SBR system in a low-altitude polar orbit using near-earth targets in the presence of earth clutter. Results indicate the effects on detection performance of look direction and target latitude.

Dynamic RCS: A Geometrical/Eulerian Approach to Computing High Frequency Radar Cross Sections
Author:
Publisher:
ISBN:
Category :
Languages : en
Pages : 28
Book Description
Level Set Systems (LSS) has developed a 3D-Eulerian, time-domain method for computing the propagation and scattering of short electromagnetic pulses over arbitrarily long distances. Efforts accommodated includes variation of index of refraction and scattering from complex features including tanks and aircraft. LSS developed a level set method for the construction of wavefronts that handles resolution, multivalued solutions, reflection and refraction. The key idea involves an Eulerian, fixed grid solver involving a system of linear Liouville equations, three equations in five space dimensions. The complexity of each update is no worse than that of ray tracing because of the use of a new local level set method for high dimension and codimension. This allows this level set method to be a viable alternative to ray tracing with many advantages for realistic DOD applications involving geometric optics. Flow Analysis Inc (FAI) has developed a lattice confinement method that has been shown to be effective for propagating short pulses as nonlinear solitary waves over long distances. These two methods complement each other and lay the foundation for greatly improved Radar Cross Section computations.
