ELECTROMAGNETIC COMPATIBILITY MEASUREMENTS AND ANALYSIS OF SYSTEMS IN THE 1535-1660 MHZ BAND

Laboratory measurements were performed on a number of systems operating in the 1535-1660 MHz band to determine electromagnetic compatibility. These systems included: five types of radar altimeters operating in the 1600-1660 MHz band, three proposed air-to-air Collision Avoidance Systems (CAS) operating in the 1592.5-1622.5 MHz band, and a simulated Satellite Communication System operating in the 1622.5-1660 MHz uplink band and 1535-1578.5 MHz downlink band. The measurements revealed a distinct incompatibility between the three proposed CAS's and the APN-155, APN-159 and Bonzer TRN-70 radar altimeters; therefore, further analysis was performed to determine the effects of altimeter interference to CAS in an operational environment.
