The informative signal of the vast majority of sensors on piezoelectric transducers is the ToF (Time-of-Flight) of ultrasonic oscillations, and its formation is realized by measuring the delay between the pulses of oscillations emitted by the actuator and the pulses of these oscillations received by the sensor. However, the processes of forming this informative signal and the electronic means of implementing these processes are characterized by a significant influence of extraneous factors, the compensation of which is largely problematic.

In the paper the requirements analysis that must be considered at designing embedded systems was performed. Describes peculiarities of the structuring requirements and developed a model of requirements to the created embedded system. Methodology of creating requirements, taking into account the processes of their definition and analysis was proposed. The results of application of the developed requirements model during project implementation the embedded system to control of mobile platform were presented
