Characteristics of a target are essential for the classification purpose. Input parameters such as blade length, rotation rate and a number of rotors can be used for classification of drone. An algorithm for accurate measurement of blade length and rotation rate using pattern analysis has been proposed. The time–frequency domain image is used for calculation of maximum Doppler frequency and the rotational speed of the blade. Accuracy and precision of the proposed technique are validated by experimental data using W‐band radar system.
