<jats:p>Conducted measurements of qualitative informative features for object recognition determined the most effective methods for measuring them. For this purpose, it is proposed to use the method of digital spectral analysis “thermal noise”, which will provide a significant increase in resolution and measurement accuracy of object characteristics. Experimental studies have shown that to increase the likelihood of correct identification of objects by existing radio-technical identification systems, it is necessary to measure the highly informative characteristics of objects - their radar long-range portraits. Measurement of such portraits is proposed to carry out through the use of broadband and especially ultra-wideband signals, with high stability of the complex frequency characteristics of the receiving and transmitting paths of radar stations. In particular, the proposed structure of the construction of an experimental measuring complex and the principle of its operation for measuring radar distance portraits of identification objects.</jats:p>
