Abstract
Official abstract text for this publication.
The present invention relates to radar systems and methods of using same that are more efficient than current radar systems and methods of using same. Such radar systems and methods of using same using employs a plurality of pluses is used to make a decision on the presence or absence of a target. Such radar system and method of using same is more efficient as the position and velocity of a potential target is carried over from pulse burst to pulse burst. Thus, the radar signal structure from the target is the same, which in turn results in a high cross correlation that can used to efficiently decide if signal return is from an actual target or is due to interference.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for improving a radar unit's efficiency comprising, for a pre-specified probability of false alarm and a set of pre-specified system parameters: a) determining a required threshold η using the following first set of equations: P F A = P ❘ "\[LeftBracketingBar]" W > η ❘ "\[RightBracketingBar]" H 0 ] = 1 - ∑ k = 0 K - N G k f β ( 1 - η ; K - N + 1 - k , k + 2 ) f β ( z ; m , n ) = ( n + m - 1 ) ! ( n - 1 ) ! ( m - 1 ) ! z m - 1 ( 1 - z ) n - 1 ; 0 ≤ z ≤ 1 G k = 1 ( L - N + 2 ) ! ∑ r = 0 k ( K - N + 1 + r ) ! ( 1 - η ) r r ! Q r ; k = 0 , 1 , … , K - N
