Description: This study is an attempt to investigate the
effect of distributed Bragg reflectors (DBRs) doping
concentration on the GaN-based vertical cavity surface
emitting lasers (VCSEL) using Integrated System
Engineering Technical Computer Aided Design (ISE
TCAD) software. Uniformly n (Up) and p (Down)
doping concentration, changed ranging 5e+17 to
1e+19 cm-3. The observation revealed that as DBR
doping concentrations rose, the output power increased
and the threshold current reduced. These are attributed
to the increase in radiative recombination and decrease
in the optical losses which has induced the
scattering process.-This study is an attempt to investigate the

Description: A method based on adap t ive filtering is p ropo sed to detect dim smallmoving target s in st rong undulant
clut ter background. Thismethod ut ilizes the difference between target and clut ter w ith regard to stat ist ic charac2
terist ics, the consistency of moving target’s t rajecto ry, and the random fluctuat ion of no ise. A test based on in2
frared sequence images is p resented. The result s indicate that the method can supp ress the st rong undulant clut2
ter, and enhance target s efficient ly, and it can great ly imp rove the perfo rmance of detect ing dim small target s.
