Waveform design compensation for moving extended targets
MetadataShow full item record
The Cognitive Radar (CR) is a new field for radar research. Its basic characteristics are introduced in this thesis. Two specific types of waveforms are used in this research; wideband and an adaptive waveform called probability weighted energy (PWE) waveform. This thesis also illustrates a comparison of two approaches to using a target recognition CR system. The first approach is to set a specific probability threshold but without limiting the number of transmissions. In contrast, the second approach is to set a specific number of transmissions. Moreover, waveform design due to moving target and a static target recognition CR system using wideband waveform and PWE waveform is presented. For a target whose extent changes with motion, a CR system must compensate the waveforms in order to mitigate the effect on performance.

Integrated range-Doppler map and extended target classification with adaptive waveform for cognitive radar Nieh, Jo-Yen (Monterey, California: Naval Postgraduate School, 2014-12);We set out to design an extended target classification scheme while determining the target’s range-and-Doppler location with the use of adaptive waveform for a closed-loop cognitive radar platform. To that end, this work ...
Romero, Ric A.; Nieh, Jo-Yen (IEEE, 2013);In this paper we investigate the range resolution of transmit waveform designs matched to extended targets. We specifically look at eigenwaveform design which is also known as SNR-based illumination waveform design. To ...
