| Modeling Radar Clutter |
MAY 91 |
|
| Authors:
David A. Sparrow; INSTITUTE FOR DEFENSE ANALYSES ALEXANDRIA VA
|
 | Radar detection of aircraft on a particular scan depends in large measure on the clutter return from the target's range cell. The distribution of clutter reflectivities is often so wide that variations of many dB in signature or threshold of detection correspond to changes of only a few percent in PD (probability of detection). Thus, where clutter variability is large, it must be included to avoid errors. However, large clutter ... |

| Improved effectiveness of close air support (CAS) aircraft has increased counter-air developments and the possibility of air-to-air combat (ATAC). Maneuverability and agility are desired attributes of CAS aircraft which must operate close to terrain or engage in air combat. The objective of this thesis was to investigate maneuverability and agility of modern CAS aircraft. The investigation was accomplished by expanding the capabilities of HELCOM to incorporate fixed wing aircraft modeling. ... |
