SUR 11  Surface Movement Radar Systems Requirements
Part 1 Preliminary Material
1 Introduction
This document refers to the equipment requirements and operational usage of the Surface Movement Radar (SMR) element. A SMR is usually a form of specialised primary radar with the option of secondary surveillance radar (SSR) elements or dynamic tracking with manual labelling.
2 Scope
This document only relates to those SMR systems based around the use of a suitable single sensor primary radar. The requirements apply to all equipment approved under Article 205 of the Air Navigation Order.
Part 2 Requirements
3  Safety Objective
To provide clear and unambiguous radar data to aid in the guidance and control of airport surface traffic (1717).
4  The Surface Movement Guidance and Control (SMGC) System
4.1  The SMGC system comprises the following elements: a) Visual and non-visual aids. b) Radio telephony communication. c) Operating procedures. d) Control and information facilities.
4.2  Recommendation: All elements of the SMGC should be located at the SMR control position (745).
5  Performance Requirements for SMR
5.1  Display Functions
5.1.1  The display shall be usable in a daylight environment (746). The orientation of the picture in relation to the view from the VCR will depend on the tasks carried out by the Controller. At a unit where the controller has clearly defined and fairly narrow tasks to perform, the orientation is to be such that the runway on the SMR is aligned with the view of the runway from the control position (224). In such cases where the SMR picture is not aligned with the view of the runway from the VCR then the Human Factors risks that this may pose shall be addressed in the supporting Safety Assurance Documentation (2382).
5.1.2  Recommendation: SMR systems should display the 'raw' radar return to show the traffic position (747).
5.1.3  Recommendation: All display systems should give historical trail information, with the amount of 'trail' appropriate to the OR (748).
5.1.4  Recommendation: The equipment should display ranges between 1 NM and 6 NM and have range offset controls (749).
5.1.5  Recommendation: The equipment should suppress information from non-operational areas (750).
5.1.6  Recommendation: The display size should allow discrimination between targets spaced at one quarter of the minimum visual feature size (751). NOTE 1:The display may use colours to aid discrimination between: a)Moving and stationary targets and
b)True data and overlaid information (maps etc). NOTE 2:The use of colour for information coding is not allowed (752).
5.2  Coverage
5.2.1  The coverage shall extend over a range and azimuth sufficient to cover the manoeuvring area (753).
5.2.2  The vertical coverage shall be suitable for monitoring all airport traffic on the ground (754).
5.3  Target Detection
5.3.1  The system shall be capable of detecting targets as necessary within the coverage as defined in the OR (755).
5.3.2  Recommendation: The system should provide a detection capability of 90%. A target size should be chosen appropriate to the size of traffic found in the manoeuvring area and the target orientation distribution. A target size of 1 m2 is recommended (756).
NOTE:  All practical systems will exhibit some areas of poor detection capability. Such areas are allowed if the training of staff and the operating procedures account for them.
5.4  Shadowing
5.4.1  Any radar shadowing shall be mapped and verified (757).
5.4.2  Recommendation: Operational use should take account of both dynamic and static shadowing (758).
5.5  Resolution
Recommendation: The system should resolve two targets located at a distance equivalent to one quarter of the minimum visual feature size (759).
