Radar front-end encounter the clutter distribution is more complex, the strength
of the clutter is a big difference, if we adopt a fixed detection threshold.
Quality analysis ofgreen laser pointer will be finished as soon as possible.
Interference level increased a few decibels, will substantially increase the
false alarm, thus requiring the signal processing to the constant false alarm
rate (CFAR) target detection. Gaussian class of clutter earlier CFAR detection
is the noise level constant circuit, it is suitable for slow changes in the
average power level of the receiver internal noise, known as the slow threshold
CFAR; Clutter in time and space on the dramatic changes when using the shutter
limit CFAR, the need to use the reference unit is estimated that the average
power level of the detection unit background clutter, clearly in this way the
detection threshold is adaptive change with the changes of the clutter in the
theoretical detected on the false alarm rate is maintained constant. Some
technical parameters details ofgreen laser pointer should be further discussed.
"We most of the time spent on these technologies for customer training, and
they prove that these techniques can be used for actual production. "the DMLS
managers of 3T the RPD Bruno LeRazer said," Despite the Because ytterbium high
power fiber lasers can use any metal powder, the DMLS process in the past few
years, some improvement, but to make these technologies can really suitable for
the actual production level, there are still a lot of work to do. " Thegreen
laser pointer workshop is going to plan the storage area ofgreen laser pointer
again.
Laser material processing, information and communication, health care
and life sciences, and defense of laser technology in the world within four main
areas of application, including laser materials processing the largest
proportion, but also the fastest growing, to a country of the national economy
greatest impact on the field of application of laser technology. The extent of
laser materials processing technology in the industrial field, has become an
important symbol of measuring a country's industrial level of High power lasers,
laser materials processing experienced a high-power CO2 lasers, high-power solid
YAG lasers, currently under the direction of the direct semiconductor
laser-based semiconductor lasers and fiber lasers. The weekly report of green
laser pointer is required to submit.
