CALCULATOR, SYSTEM, METHOD AND COMPUTER PROGRAM FOR OBTAINING ONE OR MORE MOTION PARAMETERS OF A TARGET

摘要

PROBLEM TO BE SOLVED: To determine an orbit of a target including a distance parameter or a speed of a flying target using a forward scattering radar.

SOLUTION: A calculator 20 obtains motion parameters 26 of a target so that the calculator 20 is configured to obtain the one or more motion parameters 26 by at least two time differences. A first time difference describes a timing of passing of a first pair of transmitter-receiver-lines by the target, and a second time difference describes a timing of passing of a second pair of transmitter-receiver-lines by the target. The second pair of the transmitter-receiver-lines is different from the first pair of transmitter-receiver-lines.
