On the basis of the analogy between time and space sampling electrical
emitters can be identified and localized. The traditional method of s
creening (passive shielding) and the new technique (active shielding),
based on the generation of interference signals capable of creating s
creening barriers, are compared. By using signal processing techniques
the minimization of the mean square error (MSE), taken as the optimal
ity criterion, shows that active screening has performances comparable
with passive screening, as long as interference signals are related t
o the signals which one wants to protect.
