Cloud radio multistatic radar joint optimization of code vector and backhaul quantization
- 1. Cloud Radio-Multistatic Radar: Joint Optimization of Code Vector and Backhaul Quantization Abstract: A multistatic radar set-up is considered in which distributed receive antennas are connected to a Fusion Center (FC) via limited-capacity backhaul links. Similar to cloud radio access networks in communications, the receive antennas quantize the received baseband signal before transmitting it to the FC. The problem of maximizing the detection performance at the FC jointly over the code vector used by the transmitting antenna and over the statistics of the noise introduced by backhaul quantization is investigated. Specifically, adopting the information- theoretic criterion of the Bhattacharyya distance to evaluate the detection performance at the FC and information-theoretic measures of the quantization rate, the problem at hand is addressed via a Block Coordinate Descent (BCD) method coupled with Majorization- Minimization (MM). Numerical results demonstrate the advantages of the proposed joint optimization approach over more conventional solutions that perform separate optimization.
- 2. Existing System: Existing waveform design techniques such as those discussed assume infinite-capacity links between a set of distributed radar elements and a Fusion Center (FC) that performs target detection. In scenarios in which the receive antennas are distributed over a large geographical area to capture a target’s spatial diversity and no wired backhaul infrastructure is in place, this assumption should be revised. In fact, in such cases, including deployments in hostile environments or with moving sensors, the antennas would be typically connected to the FC through limited-capacity backhaul links, e.g., microwave radio channels. Proposed System: In order to cope with the capacity limitations of the backhaul links, inspired by the cloud radio access architecture in cellular communication systems, we assume that the receive sensors quantize the received baseband signal prior to the transmission to the FC. Hence, the FC operates on the quantized received baseband signals. We refer to this system as Cloud Radio-Multistatic Radar (CR-MR). Hardware Requirements: • System : Pentium IV 2.4 GHz.
