1. A collar comprising:

  • a housing containing a processor configured to control generation of an ultra-wideband radar signal and reception of one or more resultant signals, said housing located at a first circumferential position on said collar;

    a transmit antenna separate from the housing, the transmit antenna configured to output the ultra-wideband radar signal directed at biological tissue, the transmit antenna having a beam width; and

    a receive antenna separate from the housing, the receive antenna configured to receive the one or more resultant signals based on a reflection of the ultra-wideband radar signal from the biological tissue, the receive antenna having a beam width,wherein the transmit antenna is located at a second circumferential position on said collar that is different from said first circumferential position, andwherein the transmit antenna is located at a fixed angle relative to the receive antenna to maximize a magnitude associated with the one or more resultant signals such that the beam width of the transmit antenna is configured to overlap with the beam width of the receive antenna at the biological tissue.
