Introduction
Standard Evolution and Technology Upgrade
MH/T 4010-2024 is the third revised version of the civil aviation industry standard. Compared with the 2016 version, it has made the following technical improvements:
| Technical Dimension | 2016 Version | 2024 Version |
|---|---|---|
| Surveillance Function | Basic A/C Mode | New S Mode ELS/EHS Service |
| Collaborative Capability | No Explicit Requirements | Support for ADS-B Data Fusion |
| System Architecture | Single-channel design | Dual-channel redundant design |
Core Performance Indicators
Coverage Capability
The system needs to meet the requirements of LVA antenna to achieve three-dimensional coverage within the range of 0.5-256 nautical miles, with the overhead blind area ≤45° elevation angle, including:
- A/C mode: detection probability ≥97%
- S mode: detection probability ≥99%
Measurement Accuracy
| Parameters | A/C mode | S mode |
|---|---|---|
| Range system error | <14m | <14m |
| Ranged range error | <30m | <15m |
| Azimuth error | <0.068° | |
Key subsystem requirements
Antenna and feed system
Adopt large vertical aperture array antenna, technical parameters include:
- Summary beam gain ≥27dBi
- 3dB beam width 2.45°±0.25°
- Differential beam null depth>30dB
Interrogator Design
The transmitter needs to meet multi-mode operation:
| Mode | Pulse Characteristics | Duty Cycle |
|---|---|---|
| A/C Mode | P1-P3 Interval 8/21μs | >1% |
| S Mode | P6 Pulse 16.25/30.25μs | Instantaneous 63.7% |
Implementation Suggestions
Key Points for System Integration
- Give priority to those that support ASTERIX Cat048 protocol processing system
- The lightning protection of the antenna and feed system must comply with the SPD installation specifications of MH/T 4020
- The test transponder should have dual-channel hot backup
Operation and maintenance management
- Establish a regular calibration system (especially the azimuth encoder)
- Monitor the rationality of the STC curve setting
- Regularly verify the response capability of the BDS register
