Abstract	At the Department of Theoretical Fundamentals of Radio Engineering, sonar systems to identify the location and the structure of underwater objects (UO) have been designed and developed. In the systems, by comparison with the traditional ones, additional information from the UO is obtained by means of measuring the phase frequency response of the UO. In order to realize the new method multicomponent phase-tied signals are emitted and a phase shift between the components of the echo signals is measured. In order to reduce the weight and the dimensions of the equipment, parametrical emitting antennas instead of traditional ones are offered for use. The emitting element is fed with a multicomponent phase-tied signal with high frequency (in the millimeter frequency range). As a result of the nonlinear interaction of the high frequency components in the water, harmonics of the waves with a frequency difference between them are formed, i.e., a multicomponent phase-tied waves. In order to measure the reflection phase-frequency response of an UO in a wide frequency band one must vary the frequencies F and 2F of the signals and filter the waves. In the receivers of the systems phase shift measurers (PSM) are applied. Two amplifiers with double frequency conversion and highly selective elements filter the waves with frequencies F and 2F. The realization of the receiver and the PSM has many difficulties. Therefore another realization of the units is developed which does not contain highly-selective elements.
