Subsequently, Rayleigh and Log Normal-distributed clutters based on Gaussian spectrum are simulated with ZMNL, and Weibull and K-distributed clutters based on coherent pulsed radar clutter model are also simulated with ZMNL and SIRP respectively.
Experiments result shows that side lobe of all filters is lower than-50dB,improvement factor of the MTD system against ground clutter is better than 55dB,which proofs that this MTD system has perfect detection effectiveness.
To suppress the ground clutter, for airborne early warning (AEW) radars is the key technique in radar signal processing.
In such an effect, the range-dependent ground clutter spectrum can be easily aligned, and Space-Time Adaptive Processing (STAP) is to be more applicable and effective for the Ground Moving Target Indication (GMTI) in bistatic systems.
The new waveform is shown to have good ability to suppress ground clutter and good Electronic Counter-CounterMeasures (ECCM) ability as well.
Ground clutter does not principally interfere with RASS echoes due to their big frequency shift.
Therefore, RASS can supplement radar wind profilers at lower levels where clear-air echoes may be not detectable due to ground clutter.
The robot is started in completely unknown and cluttered environments.
As a reptile animal crawls in a cluttered environment, so a quadruped robot should be able to crawl on an irregular ground profile with its static stability by adopting the straightgoing and standstill-turning free gaits.
This feature enhances the maneuverability of the Cycab in cluttered environments.
Studies investigating this question, however, have generally only examined reaches to single objects presented in isolation, even though natural prehensile movements are typically directed at objects in cluttered scenes which contain many objects.
The intensity of one information source (vehicles in Experiment 1, destinations in Experiment 2) was varied to examine the effects of salience and discrimination on both searching for and processing the information in a cluttered display.
