JSTARS MISSION

A

JSTARS provides an airborne, stand-off range, surveillance and target acquisition radar. The primary mission of JSTARS is to provide simultaneous command and control, intelligence, surveillance, and reconnaissance (C2ISR) support to air and ground commanders.

C2 - supports attack operations, provides support for ground commander’s requirements and contributes to interdiction efforts

ISR - JSTARS acts as a theater asset, conducting surveillance of the enemy ground situation

JSTARS supports the JFACC, the JFLCC, and to a lesser extent the JFSOCC & JFMCC

Q

Support to Joint Force Air Component Commander (JFACC)

A

Air Interdiction (AI)—JSTARS supports AI by applying the kill chain. The surveillance section AOTs detect moving entities and the AWOs provide attack support to the shooter via modified 9-line

Suppression of Enemy Air Defense (SEAD)/Destruction of Enemy Air Defense (DEAD)—JSTARS can assist with SEAD/DEAD by detecting mobile SAMs/AAA by using MTI to detect rotating antennas

Combat Search and Rescue (CSAR)—JSTARS is a force multiplier in the event of a CSAR. JSTARS can act as the airborne mission coordinator (AMC) and direct CSAR forces

Q

Support to Joint Force Land Component Commander (JFLCC)

A

ASOC—JSTARS can serve as an airborne extension of the ASOC by assisting with line-of-sight (LOS) communications, providing procedural deconfliction or CAS stacks, passing MTI and SALT (size, activity, location, time) data to TACPs.

CAS—Action against hostile targets in close proximity to friendly forces and require detailed integration with fire and movement of those forces. JSTARS contributes to CAS by providing attack aircraft with target briefings, threat updates and procedural deconfliction

Joint Forcible Entry (JFE)—Joint forcible entry operations seize and hold lodgments against armed opposition. JSTARS assists the Army throughout the five phases by providing over-watch and information about the ground situation.

Q

Support to the JFSOCC & JFMCC

A

SOF—JSTARS can support both air and ground special operations. JSTARS can provide ingress/egress route screening and sanitization for airborne assets and targeting data for AC-130 operations. Ground teams are supported through IPB prior to operations, early warning for ground teams in the field and communications relay.

Joint Littoral Operations—JSTARS can track and report maritime movement, monitor beaches and pass activity prior to landing, provide information on counter-special forces maritime operations, and provide attack support information to maritime strike assets

Q

E8 - Senior Director

A

The SD is qualified as a surveillance officer (SO) and an air weapons officer (AWO), which enables him/her to take over the responsibilities of either as needed. Specifically, the SD directs the employment of the weapons systems, which could be fighter aircraft, UASs, or other aircraft capable of non-traditional ISR (NTISR).

The SD will coordinate with other C2 platforms such as AWACS or the ASOC to request strike aircraft when needed.

The CGS system is the ground component that makes JSTARS a joint platform. It consists of two M1113 (Army) or M1097A2 (USMC) high mobility multipurpose wheeled vehicles (HMMWVs or ‘Humvees’) with one acting as a mission shelter and the other as a support vehicle

CGS is employed in combat units from echelons above corps (EAC) to the brigade combat team (BCT) and fires brigade level.

receiving moving target indicator (MTI) and synthetic aperture radar (SAR)/fixed target indicator (FTI) data from the E-8C via the surveillance control data link (SCDL).

23
Q

E8 JSWS

A

The joint service work station (JSWS) is a modular and portable workstation with the same software, hardware, capability, and functionality as a CGS if it is equipped with comparable communications equipment.

Augments AOC with** **data from multiple real-time sensors and platforms including MTI, SAR, unmanned aircraft systems (UAS), imagery intelligence (IMINT) platforms, and signal intelligence (SIGINT) from RIVET JOINT and GUARDRAIL.

24
Q

E8 Radar

A

JSTARS uses the AN/APY-7 radar

side looking, planar array radar / operates in the X-Band

steered electronically in azimuth by phase shifters on the antenna array

steered mechanically in elevation

operates in two modes; MTI and SAR

two radar modes cannot operate concurrently, but instead interrupt each other

25
Q
A
26
Q

E8 MTI

A

MTI is the primary radar mode and is used to detect moving ground targets

MTI identifies the pulse Doppler shifts in the radar returns. MTI can be low resolution or medium resolution.

27
Q

E8 SAR

A

SAR is the highest resolution of radar operations and can be high, medium or low resolution. A SAR is basically a radar “picture” of the surface

terrain analysis, change detection, and limited battle damage indication (BDI). A fixed target indicator (FTI) is a SAR that shows radar returns above a certain threshold. FTIs are used to locate stopped MTI tracks by showing red pixels where the brightest radar returns are located.

28
Q

E8 Radar Service Requests

A

Radar Reference Coverage Area (RRCA) sector radar job that moves w/ A/C. System Cal. Lo Res / Lo Priority

Ground Reference Coverage Area (GRCA) large area RSR used to detect pockets of activity/inactivity and determine lines of communication. GEO FIXED / Low Res / Low Priority (40-60 s)

Sector Search (SS)medium-sized RSR that can be used to “spotlight” areas to search for targets and can provide a more accurate assessment of MTI. Lo-Med Res / Med Priority (10-15 s)

**Attack Planning (AP) and Attack Control (AC) **smallest RSRs available. (AP - MTI counts / AC - attack Support) Med Res (2-5 s)

Typically 60s Timeline decided by ARMY

29
Q

E8 Orbits

A

The mission planning SO and navigator determine the best possible orbit that will optimize radar coverage and data-link connectivity while also providing the best protection from threats. The important orbit placement factors are line of sight for the radar, possible terrain masking, comm requirements, and time in the turns.

JSTARS turns are 5NM while AWACS turns are 15NM

A

Advantages—point-to-point pattern used for extreme terrain problems/staying on confined areas, coastal areas, least predictable

Disadvantages—not able to use for standard surveillance with GRCA

33
Q

E8 Named Area of Interest (NAI)

A

NAIs are defined as an area at which enemy activity is expected. In mission planning, the SO will ensure that the radar game plan he/she develops will cover all NAIs requested on the collection deck from the AOC. On the jet, the surveillance section will be tasked to maintain tracking in these areas using the information provided in the collection deck.

34
Q

E8 Collection Deck
