Adaptive Waveform Design for Cognitive Radar in Multiple Targets Situation
In this paper, the problem of cognitive radar (CR) waveform optimization design for target detection and estimation in multiple extended targets situations is investigated. This problem is analyzed in signal-dependent interference, as well as additive channel noise for extended targets with unknown target impulse response (TIR). To address this problem, an improved algorithm is employed for tar...
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 کاملPower Allocation Strategies for MIMO Radar Waveform Design
The role of waveform design is central to effective radar resource management for state-of-the art radar systems. The waveform shape employed by any radar system has always been a key factor in determining the performance and application. The design of radar waveform to minimize mean square error (MSE) in estimating the target impulse response is based on power allocation using waterfilling. ...
متن کاملWaveform Design using Second Order Cone Programming in Radar Systems
Transmit waveform design is one of the most important problems in active sensing and communication systems. This problem, due to the complexity and non-convexity, has been always the main topic of many papers for the decades. However, still an optimal solution which guarantees a global minimum for this multi-variable optimization problem is not found. In this paper, we propose an attracting met...
متن کاملOthogonal 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;
