Vehicular radar sensing system with evolving radar scan configurations

A method for generating an optimal scan configuration for a vehicular radar sensing system, the method comprising:

• generating a plurality of random radar scan configurations, wherein each radar scan configuration of the plurality of random radar scan configurations comprises a plurality of randomized parameters, and wherein each parameter defines a configurable value for design of the vehicular radar sensing system;
• for each respective radar scan configuration of the plurality of random radar scan configurations, determining a cost value using a cost function, wherein the cost function is based on a target system specification comprising at least one system specification parameter;
• selecting a subset of radar scan configurations from the plurality of random radar scan configurations based on the cost value of each respective radar scan configuration;
• generating, from the subset of radar scan configurations, a second plurality of radar scan configurations;
• for each respective radar scan configuration of the second plurality of radar scan configurations, determining the cost value using the cost function;
• and
• providing the subset of the second plurality of radar scan configurations based on the cost values.

A method for generating an optimal scan configuration for a vehicular radar sensing system, the method comprising:

• obtaining, from a user device of a designer of the vehicular radar sensing system, a plurality of configurable scan parameters for the vehicular radar sensing system;
• receiving a target system specification for the vehicular radar sensing system, wherein the target system specification comprises at least one system specification parameter for the vehicular radar sensing system;
• deriving at least one relationship between the plurality of configurable scan parameters and the at least one system specification parameters;
• defining, for a genetic algorithm, at least one selected from the group consisting of (i) a selection parameter, (ii) a crossover parameter, and (iii) a mutation parameter generating, using the genetic algorithm, a population of solutions using the at least one relationship;
• determining, from the population of solutions, a potential system specification, wherein the potential system specification defines values for each of the plurality of configurable scan parameters for use by the designer in designing the vehicular radar sensing system;
• determining whether the potential system specification satisfies a cost threshold;
