Serving as the prime contractor to the Defence Materiel Organisation (DMO), Daronmont developed, installed and conducted site trials of a High Frequency Surface Wave Radar known as SECAR. The primary aim was to supply Coastwatch with comprehensive all weather 24 hour surveillance services and data utilising the technology of the surface wave radar.
SECAR was developed as a bistatic (separate transmit and receive sites) radar which provides greater range for the same power as monostatic radars and eliminates ‘blind zones’. The system uses the superior FMCW waveform and operates over a large frequency range of 4-16MHz. SECAR’s flexible and mature architecture allows operators to be kept in the loop which results in enhanced target detection in real-time. The system can be remotely operated and is capable of detecting both air and surface targets simultaneously.
Some of the tasks performed on the project include:
Development of operational concepts and specifications;
Simulation modelling of the HF environment (noise, isolation and performance);
Design and development of RF signal conditioning, RF signal calibration and spectrum monitoring;
Software development and integration with COTS equipment and DSTO developed radar equipment;
In-house real-time embedded radar processing software;
Control and Operator Workstation HMI;
Custom designed containerisation of the radar equipment into 3 20’ ISO shelters;
Engagement with the Indigenous authorities of proposed deployment sites;
Site surveying, preparation of remote locations for deployment where access was via helicopter or boat;
Power Generation and Remote Monitoring;
Decommissioning of the radar, and
Restoring the deployment sites back to their original condition at the conclusion of the contract.
