"The probability of target detection in airborne-radar missions depends on the target signal-to-interference-plus-noise ratio. In order to maximize the probability of detection, it is necessary to maximize the target signal-to-interference-plus-noise ratio by suppressing the interference to an acceptable level. The type of interference encountered by airborne radars is of a distinctive nature; it spreads in both the spatial and the temporal dimensions, exhibiting a relationship between the amount of Doppler shift in the temporal dimension and the spatial direction of the echo source. In practical situations, the characteristics of the interference present are not known a priori; thus, they have to be estimated in real-time. The two-dimensional nature of the unknown interference dictates the use of two-dimensional adaptive filters to suppress it. Such filters are called space-time adaptive filters. In practical situations, the amount of secondary training data needed to accurately compute the space-time adaptive filter weights is not available. Thus, it is necessary to develop algorithms that are able to suppress the unknown interference with limited amounts of training data. Many such algorithms have been developed over the past few decades, each with its own advantages and drawbacks. In this report, a new algorithm called 'learning-based space-time adaptive processing' is proposed."--Abstract.

Space-time adaptive processing (STAP) is an exciting technology for advanced radar systems that allows for significant performance enhancements over conventional approaches. Based on a time-tested course taught in industry, government and academia, this second edition reviews basic STAP concepts and methods, placing emphasis on implementation in real-world systems. It addresses the needs of radar engineers who are seeking to apply effective STAP techniques to their systems, and serves as an excellent reference for non-radar specialists with an interest in the signal processing applications of STAP. Engineers find the analysis tools they need to assess the impact of STAP on a variety of important radar applications. A toolkit of STAP algorithms and implementation techniques allows practitioners the flexibility of adapting the best methods to their application. In addition, this second edition adds brand new coverage on “STAP on Transmit” and “Knowledge-Aided STAP (KA-STAP).

This text discusses various applications of space-time adaptive processing, including applications in OTH-radar, ground target tracking, STAP in real world clutter environments, jammer cancellation, superresolution, active sonar, seismics and communications. It is divided into two parts: the first dealing with the classical adaptive suppression of airborne and spacebased radar clutter, and the second comprising of miscellaneous applications in other fields such as communications, underwater sound and seismics.

There are many variations of space-time adaptive processing (STAP) that have been proposed since as far back as the 1960s. Practically all of the variations can be grouped into eight general methods. These methods are described in this report. An interesting discussion on the relative merits of the methods and of STAP in general is also included. Contentions are backed up by results from applying STAP to measured data. The merits identified in this report are used later (Volume III) to derive rules for a knowledge-based space-time adaptive processing system.

Abstract report addresses the statistical analysis of the non-homogeneity detector (NHD) for non-Guassian interference scenarios. An important issue in STAP is that of homogeneity of training data. Non-homogeneity of the training data has a deleterious effect on STAP performance in that undernulled clutter significantly degrades detection and false alarm characteristics. Previous work in this area has proposed the use of non-homogeneity detector based on a generalized inner product (GIP). The unsuitability of the GIP based test for non-Guassian interference scenarios is noted. We present a new non-homogeneity detector for non-Guassian interference scenarios which can be modeled by a spherically invariant random process (SIRP). Our work includes a statistical analysis of the NHD for non-Guassian interference taking into account the fact that finite sample support is used for covariance estimation. In particular, exact theoretical expressions for the NHD test statistic PDF and the mean of a related test statistic are derived. We also note that the related test statistic admits a remarkably simple stochastic representation as a ratio of an F-distributed random variable and a beta-distributed loss factor. Based on this development, a formal goodness-of-fit test is presented. Performance analysis is carried out using simulated and measured data from the MCARM Program.
