Abstract
Official abstract text for this publication.
A method for determining at least one parameter for the purpose of correlating two objects ( 10, 20 ), particularly the distance (r) and/or the relative speed (v) of the two objects ( 10, 20 ). A plurality of transmission pulse sequences following one after the after, each with at least one transmission pulse of an electromagnetic signal, forms a series of transmission pulse sequences. The duration of transmission of the individual transmission pulses is varied from transmission pulse sequence to transmission pulse sequence in order to reduce the susceptibility to interference in the determination of the at least one parameter.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for determining at least one parameter for the purpose of correlating two objects, and particularly at least one of the distance, the relative speed, and relative angles of the two objects comprising the steps of: forming a series of transmission pulse sequences in which a plurality of transmission pulse sequences follow one after the after, each with at least one transmission pulse of an electromagnetic signal, varying the duration of transmission of the individual transmission pulses from transmission pulse sequence to transmission pulse sequence by addition of a varied additional duration to a fixed base duration in order to reduce the susceptibility to interference in the determination of the at least one parameter, wherein each transmission pulse within a given transmission pulse sequence has the same duration of transmission. 2. The method according to claim 1 , wherein each transmission pulse sequence has the same number of transmission pulses. 3. The method according to claim 1 , wherein each transmission pulse sequence has at least two transmission pulses. 4. The method according to claim 1 , wherein the additional duration is varied by means of a random generator. 5. The method according to claim 1 , wherein the additional duration is varied between prespecified boundaries. 6. The method according to claim 1 , wherein the manner of the variation of the duration of transmission of the individual transmission pulses is changed after a plurality of series of transmission sequences. 7. The method according to claim 1 , wherein the variation of the duration of transmission is produced by a variation of a sampling rate for the individual transmission pulses. 8. The method according to claim 1 , wherein the variation of the duration of transmission is produced by a variation of a switch converter frequency for the series of transmission pulse sequences.
