ABSTRACT:
For aircraft equipped with ATCRBS, an interrogation system including an interrogator and an auxiliary transponder located adjacent the runway and on opposite sides thereof, respectively. The interrogator is enabled through a signal cable from a remote location, such as a control tower, to produce the first of the discretely spaced pulse pair required to interrogate the ATCRBS equipment. The second interrogation pulse of the pair is generated by the transponder, which is activated by the radiated first pulse from the interrogator and includes an internal delay, such that this delay plus the transit time from the transponder serves to generate the second pulse of the pair if the aircraft to be interrogated is in the vicinity and on the pathway centerline or within a specified lateral tolerance therefrom. The ATCRBS reply may be received directly at the control tower or may be transmitted by cable from receiving equipment within the interrogator. ATCRBS decoding and display equipment may be employed at the control tower for discrete identification of a given aircraft. The identification points may be distributed along a runway, taxiway or other surface area of an airport for continuing identification.
