Radar Constant-Modulus Waveform Design with Prior Information of the Extended Target and Clutter
Radar waveform design is of great importance for radar system performances and has drawn considerable attention recently. Constant modulus is an important waveform design consideration, both from the point of view of hardware realization and to allow for full utilization of the transmitter's power. In this paper, we consider the problem of constant-modulus waveform design for extended target de...
متن کاملWaveform Design for Cognitive Radar with Deterministic Extended Targets in the Presence of Clutter
Adjusting radar transmitted waveform to its environment is one of the most important roles in cognitive radar; having the capability of updating transmitted waveforms in different applications is a key point. It has been shown in many studies that if the waveform is designed according to the target and clutter characteristics, the detection performance will improve significantly. The uncertaint...
متن کاملRadar Waveform Design for Extended Target Recognition under Detection Constraints
We address the problem of radar phase-coded waveform design for extended target recognition in the presence of colored Gaussian disturbance. Phase-coded waveforms are selected since they can fully exploit the transmit power with sufficient variability. An important constraint, target detection performance, is considered to meet the practical requirements. The waveform is designed to achieve max...
متن کاملJoint optimization of MIMO radar waveform and biased estimator with prior information in the presence of clutter
In this article, we consider the problem of joint optimization of multi-input multi-output (MIMO) radar waveform and biased estimator with prior information on targets of interest in the presence of signal-dependent noise. A novel constrained biased Cramer-Rao bound (CRB) based method is proposed to optimize the waveform covariance matrix (WCM) and biased estimator such that the performance of ...
متن کاملOptimal Waveform Design with Constant Modulus Constraint for Rank-One Target Detection
In radar systems, many researchers focused on the waveform design to improve the performance. And many algorithms just only consider the energy of the transmitted waveform. However, in practice, only the energy constraint is insufficient to guarantee that the signal will satisfy common envelope requirements, such as constant modulus that is important to radar transmitter. In this paper, we prop...
