Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple radar devices are arranged with overlapping detection areas and different directional vectors, then measurement precision of hit location is improved, but device complexity increases
Solution Approach 1:
The detection space is segmented into multiple detection areas, each covered by a specific radar device. By dividing the overall detection task across multiple radar units with different directional vectors, the system achieves comprehensive coverage and precise hit location while managing complexity through modular segmentation of the detection function.
2Adaptability or versatility
If radar devices are arranged to cover large or complex hit fields, then adaptability to different hit field configurations is improved, but device complexity increases
Solution Approach 1:
The radar device arrangement is designed to be universally applicable to different hit field configurations. The same basic radar units with overlapping detection areas can adapt to various target area sizes and shapes by adjusting their positions and orientations, providing multi-functional coverage without requiring completely different system designs for each application scenario.
3Reliability
If detection areas of radar devices overlap, then reliability of hit detection is improved, but device complexity increases
Solution Approach 1:
Multiple detection areas from different radar devices are merged to create overlapping coverage zones. This combining of detection capabilities ensures that hit events are reliably detected through multiple independent measurements, improving detection reliability while the systematic merging approach manages the complexity of coordinating multiple radar units.

AI summary
The invention relates to a method for determining the point of impact of flying objects (11) in a defined target area (10), wherein: a number of radar devices (20, 20') each with a recording range (21, 21') with a middle axis (22, 22') are arranged in at least one area in the surroundings of the target area; distance values of an object flying though the recording range are recorded; by evaluating said distance values and the known geometric arrangement of the radar appliances, the flight path of the object is determined; and then as a result of the determined flight path, the resulting point of impact in the target area is calculated. The invention is characterised in that the recording regions of at least adjacent radar appliances overlap or touch at least in certain areas, and the middle axes thereof have different direction vectors (23, 23'). The invention also relates to a device for carrying out the method.
