Task scheduling is an important problem of radar resource management. Because of the limited resources constraints, an effective scheduling algorithm is necessary to allocate the resources of radar system. Traditional genetic algorithm (GA) can improve the time utilization rate (TUR) and scheduling success rate (SSR), but the time shifting rate (TSR) will increase at the same time, which goes against...
Radar scientists have recently explored the application of compressed sensing for generating high resolution range profiles (HRRPs) from a limited number of measurements. The last decade has witnessed a surge of algorithms for this purpose. Among these algorithms complex-valued approximate message passing (CAMP) has attracted attention for the following reasons: (i) it converges very fast, (ii) its...
In this paper, to solve the problem of co-channel interference caused by homo-type radars working in ship formation, an interference suppression method based on joint fractional Fourier domain and time domain is proposed. The interference with different modulated frequency rates from echo signal can be eliminated at fractional Fourier domain and the ones with similar modulated frequency rate can be...
Frequency spectrum resource is the most important and fundamental resource for various information systems such as communication systems, radar systems and so on. In order to overcome the conflicts between the scarcity and low usage efficiency, cognitive capability becomes more and more important for future information system designs. In this paper, we give a comprehensive work on the problem of how...
The distributed coherent aperture radar consists of several cooperating small aperture radars and a control center, which is proposed as a new technology to replace traditional large aperture radars for the next generation radar. The coherent performance of distributed coherent aperture radar is mainly affected by time synchronization. However, current time synchronization technology could not meet...
The performance of the optimal and reduced-dimension Space-Time Adaptive Processing (STAP) algorithms for the airborne phased array radar is investigated in this paper. The clutter suppression in the mainbeam and the sidelobe clutter regions and the computation load are analyzed and compared between the optimal and two kinds of typical reduced-dimension STAP algorithms, i.e. the 2-D temporal-spatial...
