Analysis of the dependence of the vertical baseline bistatic airborne radar clutter spectrum on range
In actual environments,the vertical height between airborne transmitter and airborne receiver is always different,and as a result,a vertical baseline appears between the two airplanes.This paper first analyses the common frame of bistatic airborne radar,and then takes bistatic airborne radar as a special example,which shows the influence of the clutter Doppler frequency from the different height between the two airplanes.The paper carries out computer simulation on four key models of bistatic airborne radar,and then explains the influence of the vertical baseline based on the clutter spectrum analysis.It is discovered that bistatic airborne radar with a proper vertical baseline will decrease the dependence of the clutter spectrum on range and improve the ground moving target indication performance.
By exploring CBBRS-1/CCD, the database of satellite remote-controlled information of Chinese and Brazilian global resources, has solved the problem of basically informational database, which troubled Xinjiang's remote controlled study for a long-time. And it is applied in the processing informational database, extracting information and analyzing special program with a wide variety of directions,levels and orientations. It also produces a series of maps of resource, environment in particular program as well as supplies a group of remote-controlled investigating data including land exploitation, water resource, forest resource, grass-land resource, mineral resource and land desertification. This provides important scientific and technological support and application to Xinjiang for, under new circumstance, undergoing land planning, sustaining ecological environment and developing regional economy.
