Abstract
This document presents the results of a feasibility study on the implementation of High Range Resolution (HRR) functionality in the Experimental Array Radar System (EARS). The EARS contains two eight element receiving arrays and a TWT which transmits from 8.9 GHz to 9.4 GHz. The system has been used by the Defence Research Establishment Ottawa (DREO) for research into target height estimation and side-lobe cancellation. It is proposed to adapt the EARS for HRR research in range using the Stepped Frequency Waveform (SFWF) pulse compression technique. A short description of the SFWF technique is presented. The practical application of the SFWF technique is investigated for the EARS. The necessary hardware and software adaptations that must be implemented are described, including the timing requirements. The primary consideration for implementing HRR is the specification, purchase and integration of a new fast frequency switching RF synthesizer to replace the current CTI X-band synthesizer. An extensive market survey was conducted to find an appropriate synthesizer at a reasonable cost. Other options are presented to implement HRR without the expense of a new synthesizer. Recommendations are given for the HRR implementation. The EARS can be used with minor modifications to work as a less capable HRR research platform. TRUNCATED
