Para os que gostam de radares:
O Radar 3D das Fragatas
(todas são funcionalidaddes Essenciais)
The radar shall have the possibility to select different FSM, having one of them being “Fixed Frequency” mode.
The radar shall have “Moving Target Indicator” (MTI) or equivalent.
The radar shall have a Threshold (Fixed, Adaptive and Automatic) control in order to obtain a "Constant False-Alarm Rate" (CFAR) in clutter and multiple target situations.
The radar shall include a transmission blanking function (emission control) based on sectorization.
The radar shall support multiple simultaneous sectors.
The transmission sectorization shall be available independently for RADAR and IFF.
The radar shall provide a functionality by the operator to turn off all radiation immediately (radar silence).
The radar should have an efficient signal data processing and an effective anti-jammer management to counter new generation threats in different kinds of ECM (Electronic Counter Measures) and severe clutter environments.
The radar should have provision of gunnery (splash spotting) support for engaged surface targets.
The radar shall have a minimum bandwidth of 10% of the centre frequency (frequency agility of 10% of the centre frequency).
The radar shall comply with ECC Decision ECC/DEC/ (11)01 provided the band from 1400-1427MHz is in the spurious domain for the selected operating mode.
The radar transmission shall have a uniform radiation coverage throughout the 360 degrees.
The radar shall have a minimum calculated range coverage of 0,3NM. Shall have a maximum calculated range of 64NM for the detection of aerial targets and 32NM for surface targets (not considering Earth curvature).
The radar shall be capable of detecting and tracking flight targets with an acceleration and manoeuvring capability from 0 g up to 3 g.
The radar shall ensure an azimuth accuracy of less than or equal to 0.3 deg. (standard deviation).
The processing time shall be less than 2 seconds from signal input at the antenna to data output for plots.
The radar shall update the plot information at least once per scan.
The radar shall be capable of processing and reporting at least 300 aerial plots.
The radar shall be capable of processing and reporting at least 100 surface plots.
The radar shall be operated, monitored and maintained, locally via a radar control panel (could be a laptop).
The radar shall be equipped with HMI (Human Machine Interface) HW (Hardware) and SW (Software) elements to ensure efficient radar operation and maintenance activities.
The RADAR shall include a time synchronization mechanism in order to be able to be synchronized with external systems.
The radar shall provide the Blanking signal for ESM systems, include Pre-Sync pulse and transmission pulse envelop.
O Radar 2D;
(É essencial para os NPO mas opcional para as Fragatas)
The radar system shall provide, at least, two-dimensional long-range surveillance coverage of AIR and SURFACE targets.
The radar configuration to be delivered shall be based on the currently market available baseline, and fitted with the last available proven and recent technology.
The radar shall have an efficient signal data processing and an effective jammer suppression to counter new generation threats in different kinds of ECM (Electronic Counter Measures) and severe clutter environments.
The radar shall have frequency and time diversity.
The radar shall implement pulse compression.
The radar shall be support up to multiple simultaneous sectors.
The transmission sectorization shall be available independently for RADAR and IFF.
The System shall include a transmission blanking function (emission control) based on sectorization.
The System shall be able to turn off all radiation of all components immediately (radar silence).
The radar shall have “Moving Target Indicator” (MTI) or equivalent.
In ICAO standard atmosphere, the radar shall detect targets with an RCS of 3 m² up to a range of at least 50 NM with a detection probability of at least 80% combined with a false alarm rate of no more than 10^-6 for each scan.
The System shall be equipped with Human Machine Interface (HMI) HW and SW elements to ensure efficient Radar Operation and maintenance activities.
The radar shall be operated, monitored and maintained, locally via a radar control panel (could be a laptop).
The RADAR shall include a time synchronization mechanism in order to be able to be synchronized with external systems.
The radar shall provide the Blanking signal for ESM systems, include Pre-Sync pulse and transmission pulse envelop.
