Radar GCI Development

• Up/Down Converter System

Up/Down Converter System was designed for changing signal frequency in a most efficient ways. Up Converter are able to convert the signal from Intermediate Frequency (IF) into RF. While, Down Converter are able to convert RF signal on range of 2,9 GHz - 3,1 GHz become IF Frequency that required by Signal Processor.

Application:

Up/Down Converter on Radar system are working by converting IF signal into RF signal during transmission process and RF info IF during receiving process, this process is related to amplified process, filtering and signal processing with low noise disruptions and high-level stability of the frequency. This function was very useful for supporting high detection target with high accuracy and easily integrated with digital radar system.

• Beam Controller Unit

Beam Controller Unit are commonly used for user interfacing unit between operator and the Transmitter / Receiver (T/R) Module. Beside of that, this unit are also used by Antenna within Primary Surveillance Radar (PSR) Subsystem to control the beam pattern such as Cosecant Square 20-degree, Cosecant Square 40 degree and pencil beam. These devices also providing provide tilting function for Cosecant Square Beam with its configurable direction for Pencil Beam. Parameter transmission into T/R Module Controller are processed <1ms to ensure the effective response with high accuracy.

Application:

Beam Controller Unit on Radar System was used for configuring the direction of the beam antenna pattern to be able to detect and tracking the target, scanning the weather and supporting satellite and digital phased array system communications.

• Digital Beam Forming

Digital Beam Forming Angle Detector Receiver are an equipment that designed for signal processing using most efficient process. This equipment is requiring minimum resource of 840 DSP slices, 200 LUT/Flip-Flops and 16 MB RAM. One of the main features of this equipment was its ability to change the phase from input signal. With this phase changes process, the equipment is able to create beam simulation.

Applications:

Digital Beam Forming on Radar System was a technology of digital signal processing that used for creating, directing and controlling beam signal of the radar with highly precise and flexible using digital algorithm. This technology is able to support radar system to perform beam steering without mechanical movement of the antenna to increase the processing speed, accuracy and detection range.

DBF was applicable for defence radar, weather radar, navigational radar and also surveillance radar; with its special capability of supporting multi-beam operation, interference reduction and enhanced target detection range for fast moving and small target on large scale weather conditions.
