METHOD AND ARRANGEMENT FOR ESTIMATING AT LEAST ONE PARAMETER OF AN INTRUDER
First Claim
1. A method for estimating, from a platform, at least one parameter of an intruder, the method comprising:
- generating consecutive frames of image data at different times of said intruder with at least one passive sensor;
determining a direction from the platform to the intruder based on the generated consecutive frames of image data;
estimating a time period remaining until a potential collision between the platform and the intruder;
estimating an angular extent of the intruder, as viewed by the passive sensor, based on the image data; and
estimating a first relative location vector to a minimum intruder associated with the intruder; and
/orestimating a second relative location vector to a maximum intruder associated with the intruder.

Abstract
A method for estimating, from a platform, at least one parameter of an intruder. The method includes generating consecutive frames of image data at different times of the intruder utilizing at least one passive sensor; determining a direction from the platform to the intruder based on the generated consecutive frames of image data; estimating a time period remaining until a potential collision between the platform and the intruder, estimating an angular extent of the intruder, as viewed by the passive sensor, based on the image data; and estimating a first relative location vector to a minimum intruder associated with the intruder, and/or estimating a second relative location vector to a maximum intruder associated with the intruder. An arrangement for generating input data to a sense-and-avoid system on-board a platform. A computer programme and a computer programme product. A platform carrying the arrangement.
