Abstract : The requirement of the Navy to develop versatile, rugged, and transportable landing systems suited to Marine Corps Aircraft has created specific problems of a diverse, yet highly technical nature. The problems addressed in this report include those associated with (1) Marine landing systems, including low inertia scanning antennas, and (2) polarization effects on microwave landing systems. This report is intended to give an overview of the above three areas with particular attention devoted to some of the more specific problems. The two landing systems of major interest in this study are the Marine Remote Area and Approach Landing System (MRAALS) and the Marine Air Traffic Control and Landing System (MATCALS). With regard to MATCALS, technical problems concerning the integrity of the scanning beam, the radar receiver and the data processor are discussed. Considerations are given to beam degradations associated with the transmitter, pulse distortion, and spectral spread. Analysis that has been devoted toward the MRAALS is in the preliminary stages. Candidate systems for MRAALS are being analyzed to determine overall compatibility with MRAALS specifications. In addition to the above, the question of which polarization to use in a National Microwave Landing System is addressed. Considerably more investigation is required to determine which polarization is best suited for operation in the anticipated landing system environment. (Author)
