Method and device for estimation of the transmission characteristics of a radio frequency system
First Claim
1. A method comprising the steps of:
- in a device physically remote from a radio frequency (RF) system transmitter;
calculating for a first location a predicted received power level of an RF signal generated by the RF system transmitter;
measuring at the first location an actual received power level of the RF signal generated by the RF system transmitter;
determining a correction value based on the predicted received power level and the measured received power level; and
calculating for a second location a predicted received power level of the RF signal using the correction value.

Abstract
A device and method for estimating the operational effectiveness, status, and protection range of an electronic countermeasures system in real time or near real time are provided. The device and method calculate a predicted ECM power at a given location using a propagation and scenario model. Then a measured ECM power at the given location is used to determine a correction value equal to the difference between the calculated and measured ECM powers. The correction value and the propagation model are then used with a heuristic method to refine estimates of propagation and scenario parameters. The refined parameter set is used to produce a refined prediction of ECM power, which is used to create a refined correction factor. The refined correction factor is used to determine predicted ECM powers at a plurality of locations in an area around the device to determine a boundary of protection.
