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.

Once RAM is detected, the radar sends an early warning message indicating a round is incoming. By using this site, you agree to the Terms of Use and Privacy Policy. 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. Contact us by phone These effects are minimized immediately after launch, but the low angle makes it difficult to see the rounds during this time, in contrast to a mortar which climbs above the horizon almost immediately.

Locating mortars was relatively easy because of their high, arcing, trajectory. Starting in the s, digital computers with improved calculation capabilities allowed more complex trajectories of long-range artillery to also be determined.

If a radar observes the shell at two points in time just after launch, the line between those points can be extended to the ground and provides a highly accurate position of the mortar, more than enough for raar artillery to hit it with ease. Early counter-battery radars were generally used against mortars, whose lofted trajectories were highly symmetrical and allowed easy calculation of the launcher’s location.

It then gathers enough data to accurately locate the point of origin to within 50 meters from more than 10 kilometers away. The conical shaped beam of a traditional radar had to be pointing in the right direction, and to have sufficient power and accuracy the beam couldn’t have too large an angle, typically about 25 degrees, which made finding projectile quite difficult.

With the aid of modern communications systems, the information from a single radar can be rapidly disseminated over long distances. Let us help solve your next “impossible” challenge.

Unsourced material may be challenged and removed. The latter could observe the splashes of water from missing shots, enabling corrections to be plotted. Radar operators in light anti-aircraft batteries close to the front line found they were able to track mortar bombs.

The area immediately forward of the radar array for high energy radars is dangerous to human health. Sign In Sign Out. It can also be configured to scan less than degrees, providing focused sector coverage with more frequent update rates.

Adding to the problem is the fact that traditional artillery shells make for difficult radar targets. However, in low-threat environments, such as the Balkans in the s, they may transmit continuously and deploy in clusters to provide all-around surveillance.

This allows the radar to notify multiple batteries as well as provide early warning to the friendly targets. CS1 French-language sources fr Articles lacking in-text citations from February All articles lacking in-text citations Articles needing additional references from May All articles needing additional references Articles with multiple maintenance issues.

In another back to the future step it has also proved possible to radsr counter-battery software to battlefield airspace surveillance radars. Better radars were also able to detect howitzers when firing at high angles elevations greater than 45 degreesalthough such use was quite rare.

Normally, these radars would be attached to friendly artillery units or their support units, allowing them to quickly arrange counter-battery fire.

Counter-battery radar

There is no other counterfire radar in the world as small, light, and affordable as the LCMR. Before digital terrain databases this involved manual iteration with a paper map to check the altitude at the coordinates, change the location altitude and recompute the coordinates until a satisfactory location was found.

Of course, the trajectory has to be high enough to be seen by the radar at these ranges, and since the best locating results for guns and rockets are achieved with a reasonable radzr of trajectory segment close to the gun, long range detection does not guarantee good locating results. However, with these figures long radqr accuracy may be insufficient to satisfy the Rules of Engagement for counter-battery fire in counter insurgency operations.


Its full azimuth coverage allows it to simultaneously detect and track multiple rounds fired from separate locations within a square kilometer surveillance area. The distinguishing feature was that instead of just locating individual guns, etc.


Low lifecycle cost Unattended remote operation Easily transportable with rapid emplacement in challenging locations Ruggedized with no moving parts for minimal maintenance Rooftop, tower, tripod or vehicle mountable Network ready for integration with FAAD network Capable of fulfilling multiple missions simultaneously.

Radars can detect projectiles at considerable distances, and larger projectiles give stronger reflected signals RCS. This article includes a list of referencesbut its sources remain unclear because it has insufficient inline citations.

Please help improve this article by adding citations to reliable sources. Instead of a conical beam, the radar signal was produced in the form of a fan, about 40 degrees wide and 1 degree high.

Deploying lmr singly and moving frequently reduces exposure to attack. The usual measures against detection are using a radar horizon to screen from ground-based detection, minimising transmission time and using alerting arrangements to tell the radar when hostile artillery is active. The consequences of this detection are likely to be attack by artillery fire or aircraft including anti-radiation missiles or electronic countermeasures.

THey gotg good results with it in theater. Action on locating hostile artillery depends on policy and circumstances. However, there are exceptions.

Modern radars usually record the target as well as the firing position of hostile artillery. From Wikipedia, the free encyclopedia. However, once phased array radars compact enough for field use and with reasonable digital computing power appeared they offered a better solution.

The cylinder-like radar structure electronically steers electromagnetic pulses across a degree protective envelope.

The radar can be assembled or disassembled quickly by two soldiers in 20 minutes.
