ABSTRACT:
A passive aircraft proximity detector for use in highway vehicles. This invention includes a unique internal antenna (1) feeding a superheterodyne receiver (2). A novel reference system (3) provides phase synchronous local oscillator injection. A signal analysis system (4) determines the presence of a valid signal and activates a tracking indicator (5). The analysis system also provides range data to an indicator which displays the approximate range of the aircraft (6). A mutable timed audio alarm is also incorporated (7).
