System and methods for remote monitoring drones and aerial vehicles for security and health monitoring purposes

摘要

A method of remote identifying an aerial vehicle 601 involves receiving a first signal of an instantaneous location of the vehicle, a second signal of an instantaneous rotating speed of one or more propellers 602 of the vehicle and a third signal related to propeller characteristics of the vehicle. Successive samples of each signal are taken and a processor solves a dynamic equation of motion using a least squares or Bayesian method to estimate dynamic model parameters, including a vehicle mass and a speed-thrust characteristic curve of at least one propeller. The processor 603 matches the parameters to a database of different vehicle manufacturers to identify a vehicle model and a degradation level of the vehicle. The instantaneous location signal may be received by a radar system, laser radar (LIDAR) system or a camera-based surveillance system. The propeller characteristics may be identified via a camera based recognition system 605 or a vibration based recognition system.
