Publication number: 20100259439Abstract: A two-element array antenna system includes a first antenna element and a second antenna element. The first and second antenna elements respectively include first and second frequency multipliers. A transmitting, receiving, and processing (TRP) system is coupled to the first and second antenna elements via, respectively, a single first transmission element and a single second transmission element. The TRP system is configured to transmit to the first antenna element a first input signal at a sub-multiple of a first frequency, receive from the first frequency multiplier a first calibration signal based on the first input signal, transmit to the second antenna element a second input signal at a sub-multiple of the first frequency, receive from the second frequency multiplier a second calibration signal based on the second input signal, and determine, based on the calibration signals, a relative phase difference between the first and second transmission elements.Type: ApplicationFiled: April 8, 2010Publication date: October 14, 2010Applicant: HONEYWELL INTERNATIONAL, INC.Inventors: Ruy Lopes BRANDAO, Pal Meiyappan, Ruy C.

Patent number: 7548183Abstract: Systems and methods for automatically disabling the TCAS Broadcast when aircraft join up in formation. A Traffic Collision Avoidance System (TCAS) determines if the aircraft is approaching formation flight with other aircraft or flying in formation with other aircraft and disables a TCAS interrogation signal if the aircraft is determined to be approaching a formation or flying in formation. The TCAS receives TCAS interrogation signals from one or more other aircraft and receives aircraft configuration information from one or more other aircraft systems. The TCAS determines the aircraft is approaching formation flight or flying in formation based on the received TCAS interrogation signals, a mode of TCAS operation, and/or the received aircraft configuration information. The TCAS also automatically switches into Traffic Advisory Only mode if the aircraft is determined to be approaching formation flight or flying in formation.Type: GrantFiled: February 28, 2006Date of Patent: June 16, 2009Assignee: Honeywell International Inc.Inventors: Larry D.

Patent number: 6483453Abstract: The present invention provides a method for efficient use of the transmit power of a Traffic Alert Collision Avoidance System (TCAS) that allows enhanced surveillance range and limits radio frequency (RF) interference in crowded airspace. The method reduces power density in crowded airspace by modifying Mode S, Mode A and Mode C interrogations. During Mode S broadcasts, tracking interrogation power is reduced as a function of range. Further transmit power reduction is achieved by broadcasting a variable power density whisper-shout interrogation technique for Mode A/C aircraft when garbling is detected. If garbling is observed during a medium whisper-shout interrogation sequence, the method of the present invention attempts to clear the garbling by using focused high-density whisper-shout steps but only in the ranges where garbling was detected. Formation members can account for other formation members that are TCAS equipped using a special E-TCAS Broadcast Interrogation.Type: GrantFiled: August 29, 2001Date of Patent: November 19, 2002Assignee: Honeywell International Inc.Inventors: David Oey, Ruy C.
