Problem setting. In radar, the acoustic mode of large-scale physical modeling has long been known and well established, which can be considered as a logical continuation of the method of mathematical modeling, and on the other hand, as a preliminary stage in relation to the modes of full-scale or semi-full-scale experimental research.

Target. Substantiation of principles and methods of creating an acoustic echo-free camera for large-scale physical simulation of radar systems.

Results. Method of large-scale physical simulation of radar functioning in air environment in acoustic echo-free chamber specially created for solution of this problem is proposed.

Practical significance. Ultrasonic modelling has great efficiency in the development of new radars and has a number of advantages compared to other research methods: relatively low cost and labor intensity of creating, operating equipment and conducting examinations; greater reliability and accuracy of the results obtained, comparable to in-kind experiments; high flexibility of equipment restructuring when modeling radar of different types and range zones; possibility of using results of ultrasonic modeling (digitized echoes) for carrying out semi-static and mathematical modeling.
