Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual adaptation of tracking algorithms by operators is implemented, then tracking performance can be optimized for specific environments and target types, but operator time consumption increases significantly and requires extensive training and experience
Solution Approach 1:
The radar system automatically performs tracking algorithm adaptation by analyzing environmental data and target characteristics itself, without requiring operator intervention. The system self-adjusts tracking parameters based on detected sea state, clutter conditions, and target type, making the operator unnecessary for this task while maintaining optimized tracking performance
Solution Approach 2:
The system automatically changes tracking algorithm parameters based on detected environmental conditions and target characteristics. Different tracking parameters are selected according to sea state, clutter level, and target type, enabling optimized tracking performance across varying conditions without manual operator adjustment
2Reliability
If manual adaptation of tracking algorithms is implemented, then tracking can be optimized for specific conditions, but the operator must have significant training and experience to make correct selections
Solution Approach 1:
The radar system autonomously performs the complex task of selecting and adapting tracking algorithms based on environmental and target data, eliminating the need for operators to possess specialized knowledge or experience in algorithm selection. The system handles the intellectual workload itself
Solution Approach 2:
The manual cognitive process of operator decision-making is replaced by an automated computational system that analyzes environmental data and target characteristics to select appropriate tracking algorithms. The mechanical/physical system of automated processing substitutes for the human operator's intellectual judgment
3Ease of operation
If uniform tracking processing is applied to all detected targets, then system complexity is reduced and ease of operation is improved, but overall tracking performance does not achieve maximum potential
Solution Approach 1:
Different tracking algorithms and parameters are applied to different targets based on their specific characteristics and local environmental conditions. Each target receives customized tracking processing appropriate to its type, size, speed, and environment, rather than a uniform approach, thereby optimizing performance for each individual case
Solution Approach 2:
The set of tracking algorithms is divided into multiple specialized algorithms, each optimized for specific target types or environmental conditions. The system segments the tracking function into multiple specialized processing paths and selects the appropriate segment for each detected target based on its characteristics

AI summary
A method includes at least a preliminary step of storing a set of tracking algorithms as a function of types of targets and of environments, each tracking algorithm being a function of a type of target in a given environment; a step of detecting signals backscattered by the targets resulting in primary detections being obtained; the detection step being followed, for each detected target: by a step: of characterizing the detected target into types of target on the basis of the primary detections; and of analysing the environment of the targets in order to determine in which given environment each detected target is located; a step of adapting the tracking to each detected target, the adapting being completed by selecting the tracking algorithm as a function of the type of target to which the target belongs and of the given environment in which it is located.
