1. A method for determining information regarding a stationary or moving object, comprising:
- recording acoustic signals emitted by a first object or reflected by a second object, as a reference signal;
using the recorded reference signal to detect, evaluate or identify the first or second object; and
calculating or projecting a movement state or movement profile pertaining to the first or second object, based on the recorded acoustic signals;
wherein said acoustic signals comprise operational noise that is generated by at least one of said first and second objects, as an intrinsic result of operation thereof.

Abstract
A method and apparatus for the determination of a stationary and/or moving object, such as a vehicle, acoustic signals emitted by the object and/or reflected by another object are recorded and used to evaluate or identify an object. The object is detected, evaluated and identified acoustically with the aid of noises from it and/or extraneous noises, with respect to its own movement profile in relation to one or more coordinate axes (x, y axes), in the manner of a self-localization based on sound waves.

14. A passive acoustic radar system for determining information regarding a stationary or moving object, comprising:
-
at least one sonic transducer system having a directional characteristic for recording acoustic signals emitted by a first object or reflected by a second object; and an evaluation unit for detecting, evaluating or identifying the first or second object based on recorded acoustic signals;
wherein,the sonic transducer system comprises a plurality of sound sensors for multidirectional recording of acoustic signals or object-related noise signals for direction-related self-localization; and said acoustic signals comprise operational noise that is generated by at least one of said first and second objects, as an intrinsic result of operation thereof. - View Dependent Claims (15, 16, 17, 18, 22)

19. A method for detecting and evaluating an object which is situated in proximity to a vehicle, said method comprising:
-
recording and storing as reference signals, first sound signals emanating from the vehicle; recording second sound signals including sounds emanating from or reflected by said object; and using said recorded reference signals and said recorded second sound signals to detect, evaluate or identify said object, including calculating or projecting a movement state or movement profile for the object, based on said signals; wherein said sound signals comprise operational noise that is generated by at least one of said vehicle and said object, as an intrinsic result of operation thereof. - View Dependent Claims (20)
