NEW TECHNIQUES APPLIED TO AIR-TRAFFIC CONTROL RADARS

The handling of extraneous reflections (clutter) is critical to radar performance. Some specific solutions incorporated in air traffic control radar systems are the use of linear large dynamic range, near-optimum digital signal processor, the use of electronically step-scanned antennas; the use of multiple PRF'S instead of staggered PRF's together with coherent transmitters to keep second- time-around clutter returns well correlated; the use of a fine grained ground clutter map to give superclutter visibility on tangential targets; and the use of lower operating frequencies to greatly reduce weather and angel returns. Two demonstration radar systems have been implemented, an S-band radar using a mechanically rotating antenna and a UHF radar using an electronically step-scanned cylindrical antenna. Experimental results are described.
