“…So it has important application value in military and civil fields. At present, all countries in the world are developing the related technical [1][2][3][4][5][6][7][8][9] . The air launch system is different from the traditional one, which is composed of many objects, the structure is complex, the rocket is the unstable system when it rushes out of the cabin, so the launch performance and the stability are hot and difficult points.…”

Aiming at the characteristics of complex structure, changeable movement and the difference in emission and stability, put forward the emission performance index based on the study of internal air launch system; study the influence of the initial pitch angle of the carrier, characteristic diameter of stabilization parachute and some other characteristic parameters on emission properties; study the system's stability and put forward the concept of generalized stability through the research of kinetic equation, moreover, calculate stability domain through Monte Carlo calculation method.

“…Two typical kinds of platforms have been researched in recent years. One is the huge-volume slow-moving platform, e.g., High Altitude Airship (HAA) [13], and the other is ultrasonic aircraft, e.g., FALCON [14]. And the nearspace SAR has been becoming a revolutionizing remote sensing mission [15].…”

Abstract-Because the nearspace slow-moving platform borne synthetic aperture radar (SAR) can realize high resolution imaging using low pulse repetition frequency (PRF), a full-aperture ScanSAR (FA-ScanSAR) operation, which switches the range beam pulse by pulse, was proposed for wide swath imaging. This operation separates the wide swath into several sub-swaths, and each of which can be illuminated by a narrow range beam. The SAR antenna switches the range beam to point at each of the sub-swaths in turn, transmits pulses and receives echoes pulse by pulse. The design method of main system parameters and the calculating expressions of the performance indexes are addressed in the paper. A design example is given to compare the performance of the conventional strip operation, ScanSAR and FAScanSAR operation. The results show that FA-ScanSAR operation can obtain high resolution by full aperture accumulation in wide swath and improve the signal-to-noise ratio of SAR images for the nearspace slow-moving platform borne SAR.

“…For the first part of the mission, the top-level requirements for the operational system for the SLV are 1,000 lb payload (with the potential for an increase) to a 28.5 o circular orbit, 100 nm altitude (baseline orbit for concept comparison) LEO (Weeks et al, 2005). 10 The vehicle would have low recurring costs (less than $5 million), reach alert status within 24 hr, and then launch within 24 hr.…”
