MTI/SAR is a well established technique for airborne surveillance. In a helicopter these two modes of operation can be combined as well. The helicopter can also easily move in the vertical direction, making SAR mapping of the height profile of the ground surface possible. In this paper, MTI/SAR from a helicopter is studied in more detail. Relationships

Validity and Reliability of the MTI Photoscreener
Optometry and Vision Science, 1997ABSTRACT Objectives. The prevalence and necessity for early detection sion problems illustrate the need for improved methods of vision screening in preschool children. This study assessed the validity and reliability of a new device, the MTI Photoscreener in a cross‐sectional field study.

Novel synthesis and insecticidal activity of MTI‐800, desfluoro MTI‐800 and their intermediates
Pesticide Science, 1995AbstractA new route to the synthesis of 2‐(4‐ethoxyphenyl)‐2‐methyl‐5‐(3‐phe‐noxyphenyl)pentane (desfluoro MTI‐800) and 2‐(4‐ethoxyphenyl)‐2‐methyl‐5‐(4‐fluoro‐3‐phenoxyphenyl)pentane (MTI‐800) and the insecticidal activities of these compounds and some of the synthetic intermediates against the tobacco caterpillar Spodoptera litura (F.) is reported.

The detection of moving targets by a side-looking air- or spaceborne Synthetic Aperture Radar (SAR) is limited due to the bandwidth of the clutter. It has an azimuth spectrum whose bandwidth id determined by the antenna beamwidth in azimuth, the platform speed and the wavelength.

Adaptive implementation of optimum MTI processor
IEEE International Conference on Acoustics Speech and Signal Processing, 1993The authors propose an adaptive processor implementing an optimum moving target indicator (MTI) in the sense of maximizing the improvement factor (IF). A multichannel scheme for preventing coefficient fluctuation due to the presence of target echoes or impulse interferences is also discussed.

The available target Doppler space over which the target-to-clutter lutter improvement factor is equal to or greater than a design value based on the conventional moving target indicator (MTI) improvement factor I is investigated. Quantitative results are given for case of a zero-mean Gaussian spectrum using binomial weighting.

Compressive sensing in MTI processing
2015 3rd International Workshop on Compressed Sensing Theory and its Applications to Radar, Sonar and Remote Sensing (CoSeRa), 2015Based on the sparsity idea, the recently developed technique of compressive sensing (CS) is shown to be able to reduce significantly the need for huge amount of data and high sampling rates. On the other hand, moving target indication (MTI) processing has long been known in the traditional pulse radars to be able to detect weak signals of moving ...

A Velocity Adaptive MTI Filter
IEEE Transactions on Aerospace and Electronic Systems, 1973A method is presented for adaptively adjusting the parameters of a double MTI canceller to minimize the effects of frequency-shifted clutter spectra. The technique is implicitly gain normalized, such that changing power levels do not affect system performance. The use of ?look ahead? methods and ?fading memory?

Moving target indicator (mti) theory was explained in detail in the preceding chapter. For practical application, the technician needs an exposure to an actual system. All systems bear great resemblances to each other, and a good knowledge of one makes all others understandable. The largest deployment of latter-day FAA canceler-type mti systems was the

MTIS approach for DSS development
Proceedings of the 1986 ACM SIGSMALL/PC symposium on Small systems - SIGSMALL '86, 1986End-user systems development, and in specific decision support systems development, is one of the key factors for increasing productivity both in the end-user and in the mis department environment. It decreases the demand for traditional systems development projects, and provides faster response to user needs. The key factor to promote end-user systems
