The first-order Bragg lines in ship borne high frequency surface wave radar (HFSWR) are spread due to the platform motion, and the space-time distribution of the first-order sea clutter manifests itself as two ideal diagonal lines. However, because of the interaction between platform and sea ...

the departure from a Poisson process as the inter-arrival times distribution clearly shows.Furthermore, the non-random behaviour of the events space-time distribution mainly due to quiescient and clustered recursive seismic phases could be studied by using the method proposed by Von Seggern et al....
Space-time adaptive processing for airborne radar Future airborne radars will be required to detect targets in an interference background comprised of clutter and jamming. Space-time adaptive processing (S... J Ward - IEEE Colloquium on Space-time Adaptive Processing 被引量: 1866发表: 1998年 ...

Analysis and experimental on space-time joint CFAR detection method for passive radarAbstract: The clutter of passive radar presents complex patterns, and the residual clutter with fixed distribution in range-doppler spectrum has a high local intensity. The space domain CFAR causes continuou...
In-space biomanufacturing provides a sustainable solution to facilitate long-term, self-sufficient human habitation in extraterrestrial environments. However, its dependence on Earth-supplied feedstocks renders in-space biomanufacturing economically nonv
Manipulations of multiple carrier frequencies are especially important in a variety of fields like radar detection and wireless communications. In conventional radio-frequency architecture, the multi-frequency control is implemented by microwave circuits, which are hard to integrate with antenna apertures, ...
Since there is a lightning rod and a small steel plate used for the elevator at the top of the radome, the maximal elevation cannot be set to 90° so as to avoid the strong reflections. The minimal elevation is set to 10° to avoid the influence of clutter from the ground and mountain...
