Doppler Shift Tolerance of Accumulation and Outer Coding in MIMO-PMCW Radar

2D Angle and Doppler Frequency Estimation in MIMO Radar

A novel algorithm for the joint estimation of the Direction Of Departure (DOD)-Direction Of Arrival (DOA) and Doppler frequency for bistatic multiple-input multiple-output (MIMO) radar is proposed. The proposed algorithm uses the rotational factor produced by the time delay of sampling to construct an angle matrix by fully utilizing the properties of the auto-covariance and cross-covariance mat...

Discrete Frequency and Phase Coding Waveform for MIMO Radar

In multi-input multi-output (MIMO) radar system, good orthogonality between transmitting waveforms will fairly simplify the signal processing, along with improve the targets detection as well as the parameters estimation performance of the system. In this paper, a discrete frequency and phase coding waveform (DFPCW), which attains good orthogonality by varying the carrier frequency and initial ...

Othogonal Waveform Design for Multiple-Input Multiple-Output (MIMO) Radar

An effective numerical approach is developed for orthogonal waveform design for Multiple-Input Multiple-Output (MIMO) radar. The Doppler shift tolerance is considered in the design cost function. The design results indicate that the Doppler tolerance of the designed orthogonal waveforms is markedly improved. Keywords-MIMO radar; waveform design; Doppler effect;

A Novel Approach to Doppler Compensation and Estimation in Mimo Radar with Unitary Waveform Matrix Scheduling

In this paper, we present a method of detecting the range and Doppler phase of a point target using multiple antennas. As a key illustrative example, we consider a 4 × 4 system employing a unitary matrix waveform set, e.g., formed from Golay complementary sequences. When a non-negligible Doppler shift is induced by the target motion, the waveform matrix formed from the complementary sequences i...
