STATISTICAL SYNTHESIS OF OPTIMAL NOISE-COMPENSATED RADIOMETER

V.V. Pavlikov

Optimal algorithm processing own thermal signals in single-channel radiometric systems is synthesised and investigated in article. Calculated algorithm describes structure of noise-compensated radiometer which differs from known for presence the decorrelation filter, which located before square-law detector. Elements of Fisher’s matrix are calculated and on their basis limiting errors of parameters estimations are received. Expression for potential fluctuating sensitivity of noise-compensated radiometer is deduced with use limiting errors of its inner noise estimation.

Key words: radiometric system, optimization, ultimate accuracy of estimations, potential fluctuating sensitivity.
