Considered the problem of the effectiveness of the proposed and protected method for testing systems and structures, based on the use of the impulse response of the test object as an optimal test signal. The purpose of the study is to confirm the gain in the magnitude of the response of the test object to the optimal signal compared to traditional methods. To solve the considered problem, an approach based on the representation of the test object in the form of a matched filter is proposed. As a result of computer simulation of the procedure for the impact of various test signals on the test object, it was possible to show the advantage of the optimal test signal in the form of the maximum response of the test object to it.
