Space-time Adaptive Processing (STAP) is usually applied to adaptive anti-jam system of Global Positioning System (GPS). It is the most effective way to reject the broadband interference. But STAP often dose matrix compute, which has a huge computational complexity. Paper investigates a recursive algorithm-Frost Least-Mean-Square (FLMS) algorithm. FLMS can reduce the workload of array signal processing...
Global position system (GPS) adaptive array antenna forms null beam to suppress the interference in order to communicate normally. The nulling beamforming model is actually an optimization technique. Because the traditional adaptive algorithms usually obtain the partial optimum solution, in this letter, we propose adaptive ant colony algorithm (AACA) can find the desired solution which is a global...
According to the characteristic of GPS direct signal and reflection signal, unmanned aerial vehicle's altitude transducer and GPS navigation equipment are integrated to a miniature detention mapping receiver system. The GPS terrain echo signal mathematics equation has been inferred, the height measuring model which reflects the land surface characteristic has been established. Thus the GPS satellite...
