Passive/metastatic radar is much cheaper and likely to be more
   effective for many years to come. Also, passive can be cheaply deployed
   using COTS hardware and Gnu Radio.
   An open Ultra-Wide-Band transceiver chip set could not only enable
   excellent covert comms. but also, when several transmitters using them
   are time locked for coherence, can be used for passive radar.
