An adaptive sensing system is configured to acquire sensor data pertaining to objects in the vicinity of a land vehicle. The adaptive sensing system may be configured to identify objects that are at least partially obscured by other objects and, in response, the adaptive sensing system may be configured to modify the configuration of one or more sensors to obtain additional information pertaining to the obscured objects. The adaptive sensing system may comprise and/or be communicatively coupled to a collision detection module, which may use the sensor data acquired by the adaptive sensing system to detect potential collisions.
