1. A method for operating a dynamically adaptable vehicular radar system, the method comprising:

  • providing a transmitter configured for installation and use on a vehicle;

    providing a receiver configured for installation and use on the vehicle;

    wherein the receiver comprises a dynamically adaptable digital front end processor and a dynamically adaptable digital back end processor;

    providing a memory;

    transmitting radio signals using the transmitter;

    receiving radio signals using the receiver, wherein the received radio signals include transmitted radio signals transmitted by the transmitter and reflected from objects in an environment;

    controlling an operation of at least one of the transmitter and the receiver to provide at least one of a selected range resolution, a selected velocity resolution, and a selected angle of arrival resolution;

    wherein controlling the operation of at least one of the transmitter and the receiver is dynamically and adaptively variable, as defined by a selected functional requirement and a current environmental condition, and wherein the functional requirement comprises at least one of a selected processing time and a memory requirement;

    storing data into the memory that was produced by the digital front end processing unit from the received radio signals; and

    directing the digital back end processor to process the stored data based upon the controlled operation of the at least one of the transmitter and the receiver.
