The basic problem of a radar group monitoring an object group that has
all along been a problem of concern in the international circles of m
ilitary science has been solved for the first time, ii. mathematical m
odel for solving the 3-D monitoring problem has been developed based o
n the quasi-physical concept and a practical fast algorithm has been f
ound. A high-efficiency tracking and monitoring system can be designed
for use by radar troops and the administrative and commercial departm
ents. concerned using this algorithm.
