| Theater Missile Defense (TMD) testing identified the need for a new type of TMD target system. The system must provide intercept geometries which are difficult to achieve with current ground launch systems. The government undertook the development of the Alternate Air launched short range target (AltAir) to demonstrate the feasibility of meeting these requirements with an air-launched system. The objective of this effort was to develop a target system which ... |

Yu Nong; NATIONAL AIR INTELLIGENCE CENTER WRIGHT-PATTERSON AFB OH
|
 | Passive jamming and infrared jamming are important components of today's integrated electronic countermeasures systems. As precision guided weapons, especially electrooptical infrared guided weapons, have received widespread use in modern warfare, they have formed an increasingly significant threat to the survival of combat aircraft. Actual practice from modern local wars, especially the Gulf War, demonstrates that most airplanes that were lost were shot down by infrared homing missiles. At present, approximately ... |

| An experimental study demonstrates that there is a strong uncertainty of the 10.6 micrometers laser extinction by the spheric aerosol in relation to the same value of visibility or aerosol concentration. However, the data seem to indicate that there is a certain correlation between 10.6 micrometers laser extinction by atmospheric aerosol and visibility from the statistical point of view.

| The common path concept has been used in optical instrument design for 30 years. In fact, the designer tacitly accepts that the light traverses its path during a time period that is sufficiently short such that the atmospheric state remains the same. Now, while the measurement range is being extended or the perturbation is intensifying, the atmospheric state no longer remains the same in the given time interval, and thus, ... |
