WebSubclutter visibility of a particular radar Is a ratio expressed in decibels of the modulation of a minimum discernible moving target to the average 1 1. DSL R-2 Defense Systems … WebIn radars that achieve a high subclutter visibility by coherent processing over several pulses, a serious problem appears in the form of blind Dopplers, or `speeds', at which target detection is impossible. Of the possible methods of eliminating these blind speeds, the most basic one that is employed when the performance requirements are high ...

WebThe detection performance of the radar was spoiled, however, because the actual subclutter visibility achieved was only 60 to 70 dB. To achieve sufficient signal-to-noise ratios against the... WebThis text evaluates the feasibility of synchronising coherent, pulsed-Doppler, networked, radars with carrier frequencies of a few gigahertz and moderate bandwidths of tens of megahertz across short baselines of a few kilometres using low-cost quartz GPSDOs based on one-way GPS time transfer. funko pop star wars fighter pilot

Web2 Jun 2014 · Two of the GMTI processing approaches currently being explored are examined in this paper. One utilizes the displaced phase centre antenna (DPCA) clutter-cancellation … WebAnother big advantage, in the case of mobile systems, is that clutter tuning may be employed to increase the sensitivity of the system to slowly moving targets. A higher PRF … Webrequirements, subclutter visibility, and type of signal processing performed in the radar. Cost is an important factor, since an A/D converter, which contains more bits, is more expensive. In addition, the added bits must be maintained and processed, which increases the cost of the processor. Other radar parameters, such as transmitter frequen- funko pop star wars toys
