The parabolic SAR is calculated almost independently for each trend in the price. When the price is in an uptrend, the SAR emerges below the price and converges upwards towards it. Similarly, on a downtrend, the SAR emerges above the price and converges downwards. At each step within a trend, the SAR is calculated one period in advance.
He is best known, however, for his work in technical analysis. Wilder is the father of several technical indicators that are now considered to be the core tenets of technical analysis software. These include Average True Range, the Relative Strength Index (RSI), Average Directional Index, and the Parabolic SAR. [1]
Parabolic SAR – Wilder's trailing stop based on prices tending to stay within a parabolic curve during a strong trend; Pivot point – derived by calculating the numerical average of a particular currency's or stock's high, low and closing prices; Resistance – a price level that may act as a ceiling above price
State-of-the-art high-resolution SAR systems are rather limited with regarding to their acquisition capability. [citation needed] Requirements for spaceborne SAR. An example is TerraSAR-X, which is a German Earth-Observation satellite. Its major payload is an X-band (3.1 cm) radar sensor, with different modes of operation, which allows it to ...
Momentum is the change in an N-day simple moving average (SMA) between yesterday and today, with a scale factor N+1, i.e. + = This is the slope or steepness of the SMA line, like a derivative.
The zero lag exponential moving average (ZLEMA) is a technical indicator within technical analysis that aims is to eliminate the inherent lag associated to all trend following indicators which average a price over time.

Synthetic-aperture radar (SAR) is a form of radar that is used to create two-dimensional images or three-dimensional reconstructions of objects, such as landscapes. [1] SAR uses the motion of the radar antenna over a target region to provide finer spatial resolution than conventional stationary beam
