Target visibility judgment method based on millimeter wave radar model

The invention discloses a target visibility judgment method based on a millimeter wave radar model, which solves the problem that target visibility judgment is carried out by utilizing virtual sensingin an intelligent automobile simulation test, improves the precision of a virtual sensor model, and meets the requirement of simulation efficiency at the same time. The method comprises the followingsteps: target vehicle information detection: acquiring the detected information of a target vehicle; target vehicle reflection intensity simulation: traversing all the target vehicles according to ageometric cutting method, calculating the information of visible parts of the target vehicles with the visible parts, and calculating the reflection intensity of the target vehicles; and target vehicle visibility judgment: analyzing the visibility of the target vehicle according to the target vehicle reflection intensity value calculated in the step 2, and converting and outputting the informationof the visible target vehic
