A counter-battery radar (alternatively weapon tracking radar) is a radar system that detects . The new Lightweight Counter Mortar Radar (LCMR – AN/TPQ 48) is crewed by two soldiers and designed to be deployed inside forward positions, . U.S. Army air-defense experts are asking engineers at SRCTec LLC in Syracuse, N.Y., to build lightweight counter-mortar radar (LCMR). AN/TPQ LCMR Lightweight Counter Mortar Radar. The TPQ is the official Army program of record, while the TPQ is designed for.

Its full azimuth coverage allows it to simultaneously detect and track multiple rounds fired from separate locations within a square kilometer surveillance area. THey gotg good results with it in theater. When compared to its expeditionary predecessor, it detects targets with flatter trajectories while calculating the point of origin more accurately from a greater distance. The system is currently deployed by military forces around the globe.

Once RAM is detected, the radar sends an early warning message indicating a round is incoming. The first radars were developed for lcnr purposes just before World War II.


At pounds and 3. It mounts on a tripod using lightweight antenna hardware, allowing for rapid emplacement and ease of relocation. They can detect and track anything in their field of view, providing they have sufficient computing power. In other circumstances, particularly counter-insurgency, where ground attack with direct fire or short range indirect fire is the main threat, radars deploy in defended localities but do not need to move, unless they need to cover a different area.

One technique was to deploy listening posts that told the radar operator roughly where to point the beam, in some cases the radar didn’t switch on until this point to make it less vulnerable to electronic counter-measures ECM.

This information is reported back to an integrated command and control station or short range air defense system for a counterfire response. Better radars were also able to detect howitzers when firing at high angles elevations greater than 45 degreesalthough such use was quite rare.

Since a parabola is defined by just two points, then tracking a segment of the trajectory was not notably efficient. However, with these figures long range accuracy may be insufficient to satisfy the Rules of Engagement for counter-battery fire in counter insurgency operations.


It can be deployed in challenging locations previously unavailable to traditional counterfire radars, making it an ideal solution for force protection at Forward Lmcr Bases. Unsourced material may be challenged and removed.

Let us help solve your next “impossible” challenge. For more information about our LCMR counterfire radars, please contact us today. Retrieved 1 July Generally, the shells could not be seen directly by the radar, as they were too small and rounded to make a strong return, and travelled too quickly for the mechanical antennas of the era to follow.

A counter-battery radar alternatively weapon tracking radar is a radar system that detects artillery projectiles fired by one or more guns, howitzersmortars or rocket launchers and, from their trajectories, locates the position on the ground of the weapon that fired it. However, in the radars produced today, C band and S band are common.

Deploying radars singly and moving frequently reduces exposure to attack. This was short-lived for unclear reasons, but the US embarked on Firefinder program and Hughes developed the necessary algorithms, although it took two or three years of difficult work.

Once a trajectory segment is captured it can then be processed to determine its point of origin on the ground. Counter-battery radars operate at microwave frequencies with relatively high average radat consumption up to the tens of kilowatts.

Eadar help improve it or discuss these issues on the talk page. However, this is usually for intelligence purposes because there is seldom time to alert the target with sufficient warning time in a battlefield environment, even with data communications.

AN/TPQ Lightweight Counter Mortar Radar (LCMR)

However, self-propelled ones have been used since the s. From Wikipedia, the free encyclopedia. Older types were mostly trailer mounted with a separate generator, so took 15—30 minutes to bring into action and need a larger crew. This is usually done automatically, but some early and not so early radars required the operator to manually track the projectile. They can filter out the targets of no interest e. Detection ranges depend on capturing at least several seconds of a trajectory and can be limited by the radar horizon and the height of the trajectory.

Operations in Iraq and Afghanistan led to a new need for a small counter-mortar radar for use in forward operating bases, providing degree coverage and requiring a minimal crew.

The Ku band has also been used. Sign In Sign Out. Until about this relied on conventional artillery survey, although gyroscopic orientation from the mids helped. QRCs represent efforts to quickly get capability-enhancing technology to theater while simultaneously harvesting Soldier input and refining requirements for a traditional program of record.

The cylinder-like radar structure electronically steers electromagnetic pulses across a degree protective envelope. The emergence of indirect fire in World War I saw the development of sound rangingflash spotting and air reconnaissance, both visual and photographic.

Counter-battery radar

Normally, these radars would be attached to friendly artillery units or their support units, allowing them to quickly arrange counter-battery fire. It can also be configured to scan less than lcmd, providing focused sector coverage with more frequent update rates.

However, conventional radar beams were not notably effective. The operator would then flick the antenna to a second angle facing higher into the air, and wait for the signal to appear there. The operator would watch for mortar bombs to pass through the slice, locating its range with pulse timing, its horizontal location by the location of the Foster scanner at that instant, and its vertical location from the known angle of the thin beam. The radars perform with a track-while-scan capability allowing for the simultaneous detection and tracking of multiple threats fired from separate locations.

Rasar Radar Center of Excellence is the largest and most comprehensive capability in the organic industrial base for all types of radar.

This article includes a list of referencesbut its sources remain unclear because it has insufficient inline citations. A Foster scanner modified the signal to cause it to focus on rzdar horizontal location that rapidly scanned back and forth.

Once a RAM threat is detected, the radar sends an early warning message indicating that a round is incoming. Please help improve this article by adding citations to reliable sources. The consequences of this detection are likely to be attack by artillery fire or aircraft including anti-radiation missiles or electronic countermeasures.
