## Multi-function Phased Array Radar (MPAR)

**FAA Roadmap for Air Traffic and Weather Surveillance**

## Air Traffic and Weather Surveillance Snapshot

**Air Traffic is expected to more than double ****by 2025 and will exacerbate the air traffic ****delay problem.**
**Weather is the major contributor to delays****accounting for 65% of all delays.**
**Current weather and surveillance ****radar networks are aging (new to ****40 years old).**
**Many are nearing the end of their ****service life and will require ****expensive service life extension ****programs (SLEP)**
**FAA Enterprise Architecture Roadmaps ****include decision points for replacing ****current conventional rotating radars.**

## Cooperative Surveillance

**The FAA is migrating to the Automatic Dependent Surveillance - Broadcast (ADS-B) concept**
- Transforms the nation's air traffic control system from one that relies on radar technology to a system that uses precise location data from the global satellite network (i.e., GPS)
- ADS-B is a crucial component of the nation's Next-Generation Air Transportation System
**The *****Surveillance/Positioning Backup Strategy Alternatives Analysis Report *****(mitigation of GPS loss on ADS-B): **
*“**recommends that the FAA retain approximately one-half of the Secondary Radar Network as a backup strategy for ADS-B”*
*“**terminal area primary radar coverage will not be reduced from current levels”*

**Notes:**
Opportunity to partner with DOD, DHS, NOAA and other agencies in pursuit of an R&D program as well as to share surveillance resources to meet mission needs.
Research is needed to demonstrate/verify performance, multifunctionality and affordability of MPAR to offer it as a viable candidate within the solution set.
The surveillance needs of the different agencies will be satisfied by a family of systems (i.e., surveillance requirements allocated to different systems).

## FAA Enterprise Architecture 

**Surveillance and Weather Roadmaps**
**2011** - Decision Point (77) initial acquisition review decision for NextGen primary radar system including Wx and Aircraft surveillance requirements
**2014** -  Decision Point (104) to replace legacy terminal radars (ASR-8, ASR-9) with NextGen primary radar system including Wx and Aircraft surveillance requirements
**2018** - Decision Point (91) to replace Wind Shear systems, and NEXRAD with NextGen primary radar system
**2020** -  Initial Operational Capability for NextGen primary radar system including Wx and Aircraft surveillance requirements

- NextGen Wx Radar Capability

**Notes:**
Surveillance and Weather Roadmaps are aligned (multifunction solution)
Critical R&D activities required prior to the 2011 and 2014 Decision Point

## JPDO Alignment

**Next Generation (NextGen) Air Transportation ****System Integrated Plan**
*“**Develop a system-wide capability to Reduce Weather Impacts**”*
- Strategy provides for “*Research areas to develop enhanced weather observations and forecasts, and integrate them with decision support tools to enhance capacity and **efficiency of the airspace while **improving safety.”*

## Conclusion

**National primary radar network ****required for foreseeable future**
**FAA requirement is a subset of the ****National Requirement**
**Collaboration with other agencies ****is essential for best value solution**
**MPAR is a technology research ****effort**
**MPAR could be part of a ****multi-agency Family of ****Solutions**
