| Abstract: |
| On account of the fact that it is difficult for radars to detect coati
ngstealth metal targets on the ground, a new methodology of adopting millimete
r
wave(MMW) alternating current radiometer is proposed in this paper, with the p
urpose
of detecting ground based coatingstealth metal targets when their engines are
in operation. Based on the description to the configuration and operation princi
ple of radiometer, the mechanism and method of anticoatingstealth through MM
W radiometric detection is analyzed in detail, associating with the ra
diometric characteristics of targets under different conditions. And at the same
time, some corresponding theoretical results are outlined. Then a series of sim
ulative detection experiments are carried out by means of the 3mm band totalpo
w
er alternating current radiometer that has been implemented here. Furthermore, t
he experimental results are presented and they are in accord with the theoretica
l ones.Finally it is indicated that the methodology illustrated in this pap
er can effectively detect coatingstealth ground based metal targets when their
engines are running, and it provides a new route to the area of anticoatings
tealth. |
