Analys av Malroerelsers Kopping till Radaravibildningar (Analysis of the Coupling of Target Motion to Radar Imaging).

摘要

Target recognition is one of the most important challenges for tomorrow's military sensor systems. The long range and all-weather capabilities of radar systems stress the importance of radar based research for this application. Radar imaging methods, in our case of aircraft targets, have developed as one of the main tools towards operative systems. So far, these methods have not reached the required imaging performance, mainly due to the coupling between resolution and target motion. In this report, an analysis of the large scale tactical motion and the small scale technical motion of performed, with consideration to radar imaging and target recognition. The technical target motion is studied with motion data from Saab Aerospace AB. An important conclusion is that, often, we will not be able to generate two-dimensional radar images, except with limited resolution. This shows the importance of studying other waveforms that are less dependent of target motion, and also to study target glint for one-dimensional imaging.
