Air Navigation Service Providers (ANSPs) and Defence organisations need to ensure effective
and safe data communication between surveillance systems, data-sharing in Service Level
Agreements (SLA). They must be able to fully control the surveillance data flow, data
content and verify the Quality Of Service (QoS).
Surveillance systems and standards are constantly in evolution. It is becoming more challenging to maintain and verify the surveillance systems’ Quality Of Service (QoS).
As provider of radar and sensor test equipment, Intersoft Electronics® developed the Surveillance Performance Model. This model explains the need of Sensor Performance Evaluations in different steps, from requirements mandated by ICAO [“ICAO Doc. 8071 Volume III”.] and EUROCONTROL [document “Radar Sensor Performance Analysis, SUR.ET1.ST03-10000-STD-01-01” chapter 4 and EUROCONTROL Specification for ATM Surveillance System Performance volume I (EUROCONTROL-SPEC-0147)].
The methodology depicts the logical flow of how a sensor’s performance has to be established:
This last step of “Monitor Performance” is further split into 4 different levels:
By monitoring performance trends it is possible to provide early detection of system degradation before system failure occurs.
A baseline evaluation can identify the reasons for possible performance degradation of a radar sensor. The baseline evaluation also provides the ability to test the efficacy of the radar sensor's optimisation.
A special evaluation can also be used to assess the readiness of a radar sensor for flight inspection by injecting MSSR or PSR targets and comparing the results while the radar is working in its full operational state.
Our field services personnel have experience in the use of our analysis tools across a wide variety of radar systems produced by many different manufacturers around the world. We can therefore offer performance evaluation campaigns from Level 1 to 3.
