This paper proposes orthogonal Discrete Frequency Coding Space Time Waveforms (DFCSTW) for Multiple Input and Multiple Output (MIMO) radar detection in compound Gaussian clutter. The proposed orthogonal waveforms are designed considering the position and angle of the transmitting antenna when viewed from origin. These orthogonally optimized show good resolution in spikier clutter with Generaliz...

We present a flexible time-domain synthetic aperture radar signal simulation system. We demonstrate its use in simulating clutter, stationary and moving targets. The point target analysis shows that the observed impulse response agrees with theoretical values. Clutter results how that the observed clutter corresponds to K distribution model. We also demonstrate that the system may be used for t...

[1] This paper describes estimation of low-altitude atmospheric refractivity from radar sea clutter observations. The vertical structure of the refractive environment is modeled using five parameters, and the horizontal structure is modeled using six parameters. The refractivity model is implemented with and without an a priori constraint on the duct strength, as might be derived from soundings...

The concept of radar satellite constellations has been proposed in the literature and is currently under research. These constellations possess the wide angular coverage necessary for performing spaceborne MTI and the spatial sampling necessary for wide-area SAR. However, the constellations form arrays that are sparsely populated, three-dimensional, and irregularly spaced. Therefore, current SA...

The feasibility of using GPS as a bistatic radar illuminator for the purposes of air target detection is examined. The power budget analysis is first performed assuming the use of a single satellite, but is followed by a discussion of the expected improvements when multiple satellites are employed. The analysis includes the effect of GPS signal strength dynamic range, also known as the ‘near-fa...

A Doppler filter bank (DFB) is the heart of pulsed Doppler radar and gives clutter filtering and coherent integration. With these capabilities, it provides the improvement of detection probability as well as velocity discrimination, which can detect small targets in clutter environment. This paper implements a DFB with parallel processing configuration using multiple digital signal processors (...

The detection of slow moving targets by a moving bistatic pulsed Doppler radar system is addressed. Optimum clutter rejection is achieved using space-time adaptive processing (STAP). This requires estimating the clutter-plus-noise covariance matrix using a sequence of snapshots at successive ranges. For most monostatic and for all bistatic radar configurations, these snapshots are rangedependan...

An introduction to the theory of sliding window detection processes, used as alternatives to optimal Neyman-Pearson based radar detectors, is presented. Included is an outline of their historical development, together with an explanation for the resurgence of interest in such detectors for operation in modern maritime surveillance radar clutter. In particular, recent research has developed crit...
