Inspired by recent advances in multiple-input multiple-output (MIMO) communications, this proposal introduces the statistical MIMO radar concept. To our knowledge, this is the first time that the statistical MIMO is being proposed for radar. The fundamental difference between statistical MIMO and other radar array systems is that the latter seek to maximize the coherent processing gain, while s...

Elaboration of a new approach to solving of a contradictory and challenging problem of through wall detection radar design is the main goal of the paper. Two types of radars have been investigated: (1) CW radar that uses pseudo-random sequence (PRS) of the maximal length (m-sequence), hereinafter referred to as PRS-radar and (2) CW radar with use of the noise waveform at corresponding carrier f...

Landmines are affecting the lives and livelihood of millions of people around the world. The video impulse ground penetrating radar system for detection for small and shallow buried objects has been developed. The hardware combines commercially available components with components specially developed or modified for being used in the system. The GPR system has been desired to measure accurately...

Radar, and in particular imaging radar, have many and varied applications to counterterrorism. Radar is a day/night all-weather sensor, and imaging radars carried by aircraft or satellites are routinely able to achieve high-resolution images of target scenes, and to detect and classify stationary and moving targets at operational ranges. Short-range radar techniques may be used to identify smal...

2.1. Detection in the Presence of Noise A simplified block diagram of a radar receiver that employs an envelope detector followed by a threshold decision is shown in Fig. 2.1. The input signal to the receiver is composed of the radar echo signal and additive zero mean white Gaussian noise , with variance . The input noise is assumed to be spatially incoherent and uncorrelated with the signal. T...

347 Abstract— In this paper, although Radar has been used for a long time, integrated scheme with visual camera is an efficient way to enhance marine surveillance system. Camera image is focused by radar information but it is easy to be fallen into inaccurate operation due to environmental noises. We have proposed a method to filter the noises by moving average filter and Kalman filter. It is p...

Nowadays, most of the electronic devices used Digital Signal Processing (DSP). This paper discussed the block diagram, radar detection, implementation of a convolution, Doppler processing, scanning, compression and filtering that been used in the applications of DSP in Radar purposes. Keywords–Digital Signal Processing (DSP), Filter, Pulse, Radar, System

The potential applicability of multiple-channel coherence estimation in situations where one channel contains a noise-free signal replica (as in active radar) or a high-SNR reference signal (as in passive coherent radar) has been proposed in recent work. Invariance of the distribution of M -channel coherence estimate statistics, including recently derived variants optimized for detection of sig...

study on polsar target detection essentially requires the cattering information and polarimetric statistical data. theoretical analysis shows that some terms of the second order scattering matrices such as coherence and covariance matrix clearly show the differences between nonsymmetrical man-made objects and natural clatters which being reflection symmetric. using the model derived from these ...
