Annotations languages:

The method of sufficiency evaluation for the analytical guess of range higher order derivatives is developed. Using the method to the analog-to-digital system of train signal coherent processing implemented in the 5N86-M Early Warning Radar, it is established that the analytical guess is sufficient estimation for the range second derivative and insufficient one for the range third derivative.
Keywords: early warning radar, analog-to-digital system of coherent processing, range acceleration, range third derivative
