Equipment support system has a tendency for chaos and disorderly condition. Its mutually effect makes it continuously exchange for human resource, energy, material and information with outside world, minus entropy emerges continuously. Equipment support system will be orderly dissipative structure, when minus entropy surpasses entropy. This process embodies that equipment support system is evolving...
The theory of passive location to moving emitter on the ground using DOA (direction of arrival) and its rate of change is described. Expression of observability is obtained by Jacobi matrix and conditions of observability under different relative motion states are discussed. A location algorithm which involves DOA and its rate of change based on MGEKF (Modified Gain Extended Kalman Filter) is put...
