Solution Overview
Problem
Current radar target emulators are limited in their ability to efficiently emulate multiple radar targets at different distances and positions, requiring separate time delay arrays for each object and lacking flexibility in signal routing and expansion.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate time delay arrays are used for each radar target, then the emulation of multiple targets at different distances is achieved, but the device complexity and cost increase significantly
Solution Approach 1:
The patent combines multiple time delay functions into a single time delay array by using a switching device with multiple switch arrangements. Instead of having separate delay arrays for each target, the system uses one shared delay array that is controlled by switches to provide different time delays for different radar targets, thereby reducing device complexity while maintaining the ability to emulate multiple targets
Solution Approach 2:
The single time delay array is designed to serve multiple functions by being shared across different radar targets. The switching device enables this one delay array to provide time delays for multiple targets at different distances, making the delay array universal and multi-functional rather than dedicated to a single target
2Device complexity
If a single time delay array is shared among multiple targets, then device complexity is reduced, but signal routing flexibility and control precision become more challenging
Solution Approach 1:
The switching device is segmented into multiple independent switch arrangements, each associated with specific radar targets. This segmentation allows each switch arrangement to independently control the signal path for its associated targets, maintaining signal routing flexibility and control precision even though a single time delay array is shared among multiple targets

AI summary
A switching device for a radar target emulator is provided comprising: at least one first switch arrangement and a second switch arrangement, each having a branching device designed to receive a first input signal and diverge it into a branch signal and a first output signal, a switch adapted to transmit the branch signal in a first switching state within the switch arrangement and to not transmit in a second switching state, and adding means designed to emit the signal transmitted in the first switching state of the switch, at least as components of a second output signal. The first switching arrangement and the second switching arrangement are interconnected in such a way that a first input signal of the second switching arrangement comprises a first output signal of the first switching arrangement, or a second input signal of the second switching arrangement comprises a second output of the first switching arrangement.
