Abstract
Analytical review of known methods of using the ultrasonic radars to detect and round the obstacles is proposed. There are researches of precision distance measurement to the object. It is shown that for distances uncertainty 4-150 cm the distance value is less than 2%. The method of authentication such obstacles, which compares the calculated value and the value is obtained experimentally by using radar. It uses the distance measurement to the object for 3 angles of ultrasonic module rotation. The specified maximum angle of ultrasonic radar platform rotation with fixed signal is reflected from the obstacle. The level of the reflected signal depends on the angle of reflection signal from obstacles, receiver sensitivity, reflectance signal and other parameters. The algorithms based on the data for the platform movement changing and performing round the obstacles are proposed. In the algorithms all possible options for receiving the reflected signal from obstacles are comprised.
