In this paper, we focus on target detection and system configuration optimization of Multiple-input Multiple-output (MIMO) radar in low-grazing angle, where the multipath effects are very abundant. The performance of detection can be improved via utilizing the multipath echoes. First, the reflection coefficient, considering the curved earth effect, is derived. Then, the general signal model for...

For a multiple-input multiple-output (MIMO) radar system adopting the Neyman-Pearson (NP) criterion, a detection algorithm for MIMO radar with arbitrarily correlated observation channels in the presence of possible Non-Gaussian clutter-plusnoise is analyzed. Simulation results show that both the correlation of the observation channels and the correlation of the clutter-plus-noise will reduce th...

In this paper the Discrete Frequency Coded Waveforms (DFCWs) with good correlation properties are numerically designed utilizing Accelerated Particle Swarm Optimization Algorithm for MIMO Radar. To achieve this object the cost function was intended based on Peak Side lobe level Ratio (PSLR) and Integrated Side lobe Level Ratio (ISLR). The simulation results show that the DFCWs signal utilized i...

This paper derives the extended ambiguity function for a bistatic multiple-input multiple-output (MIMO) radar system, which includes the whole radar system parameters: geometric sensor configuration, waveforms, range, range rate, target scattering and noise characteristics. Recent research indicates the potential parameter estimate performance of bistatic MIMO radars. And this ambiguity functio...

Multiple input multiple output radars transmit partially coherent or noncoherent waveforms for improving spatial resolution or spatial diversity. While waveform design for SIMO radars concentrate on improving the delay and Doppler resolution characteristics, waveform design for MIMO radars involve optimization of delay, Doppler and spatial resolution characteristics. The resolution properties o...

In this paper we propose one possible approach how to apply the concept of multiple-input multipleoutput (MIMO) to monostatic Frequency Modulated Continuous Wave (FMCW) High-Frequency Surface Wave Radar (HFSWR) in a maritime environment. Common tasks for a HFSWR are sea-state monitoring and ship detection, where our focus is on ship detection. A limiting factor in HFSWR is the available bandwid...

Researchers have recently proposed a widely separated multiple-input multiple-output (MIMO) radar using monopulse angle estimation techniques for target tracking. The widely separated antennas provide improved tracking performance by mitigating complex target radar cross-section fades and angle scintillation. An adaptive array is necessary in this paradigm because the direct path from any trans...

Abstract: The MIMO phased array radar is a theoretical concept for multi-sensor radar planning that combines elements of traditional phased-array radar with the developing technology of multiple-input multiple output (MIMO) radar. Space-time coding (STC) has been shown to play a key role in the design of Phased Array MIMO radar where MIMO radar can achieve improved localization performance by ...

Abstract– In MIMO (Multiple Input Multiple Output) radar systems multiple antennas at transmit and receive sides are used to improve the detection performance. Two important parameters which have an effect on the coverage and performance of these systems are: the transmitters’ power and the receivers’ positions. In this paper, assuming the Rayleigh scatter model for the target, the probability ...

The Complete Complementary Sequence (CC-S) consists of several complementary orthogonal sequences and has optimal sidelobe level performance, which is satisfied with the requirement of the orthogonal Multiple Input Multiple Output (MIMO) radar signals. Aimed at the difficulty of high sidelobe level in Synthetic Aperture Radar (SAR) imaging processing in range dimension, an approach of depressin...
