摘要： A method and system for locating objects in a region having a high degree of multipath susceptibility comprises a plurality of transducers, each being a transmit or receive antenna, and being arranged about the region in known locations, to form a bistatic or multistatic radar, with some embodiments being MIMO systems. Signals transmitted by the transmit antenna(s) are received at each receive antenna and processed to form a set of channel impulse responses, or power delay profiles, representative of the region at a given time. A second set is formed at a different time, and the difference between the two sets is calculated, the difference containing information on movement within the region. The difference may be processed to localise the moving object(s) by graphical means, e.g. by generating an x-y image representative of the region, and accumulating at each pixel appropriate values of the profile difference selected according to the propagation delay between a transmit-receive antenna pair via a region point represented by the pixel.

摘要： A method for detecting perturbation of a physical system from a reference state associated with a reference parameter (ω0) to a perturbed state associated with a perturbed parameter (ω) includes firstly deriving the reference parameter (ω0). A reference vector (F) is then derived which describes the system's state at the reference parameter (ω0). A measurement-related vector (Z) associated with a perturbed state of the system is then subtracted from the reference vector (F) to provide an error vector (E). The error vector members are summed and normalised by division of a summation of elements of a vector (F′) representing a derivative (f(ω0δω)e) of a reference itself represented by the reference vector (F), the derivative (f(ω0δω)e) being evaluated at the reference parameter (ω0). This provides a result equal to the difference (ω−(ω0) between the perturbed parameter (ω) and the reference parameter (ω0).
