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.

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. Modern radars usually record the target as well as the firing position of hostile artillery.
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.
This was likely radwr by the fins of the bomb producing a partial corner cube that strongly reflected the signal. Deploying radars singly and moving frequently reduces exposure to attack.
Early counter-battery radars were generally used against mortars, whose lofted trajectories were highly symmetrical and allowed easy calculation of the launcher’s location. Radar operators in light anti-aircraft batteries close to the front line found they were able to track mortar bombs. Its full azimuth coverage allows it to simultaneously detect and track multiple rounds fired from separate locations within a square kilometer surveillance area. Retrieved 1 July Purely ballistic low-angle trajectories are lopsided, being relatively parabolic for the lcmmr of the flight but becoming much more curved near the end.
LCMR Counterfire Radars
Instead of a conical beam, the radar signal was produced in the form of a fan, about 40 degrees wide and 1 degree high. Low angle trajectories normally used by guns, howitzers and rockets were more difficult. This is further modified by otherwise minor effects like wind, air pressure differences and aerodynamic effects, which have time to add up to a noticeable effect on long-range rafar but can be ignored for short-range systems like mortars.
At times, just after firing and just before impact, the trajectory is almost linear. Similar situation for the new GA10 Ground Alerter 10  radar qualified and successfully deployed by the French land forces in several different FOBs worldwide.
May Learn how and when to remove this template message. Radars can detect projectiles at considerable distances, and larger projectiles give stronger reflected signals RCS. Projectile detection ranges are governed by the radar cross section RCS of the projectiles. For non-parabolic trajectories, it is also important to capture a trajectory as close as possible to its source in order to obtain the necessary accuracy.
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 radae achieved with a lmcr length of trajectory segment close to the gun, long range detection does not guarantee good locating results.
Adding to the problem is the fact that traditional artillery clmr make for difficult radar targets. Modern radars typically give CEPs around 0. This article needs additional citations for verification. From Wikipedia, the free encyclopedia. Sign In Sign Out.
AN/TPQ LCMR Lightweight Counter Mortar Radar
However, conventional radar beams were not notably effective. By the early s, radar systems capable of locating guns appeared possible, and many European members of NATO embarked on the joint Project Zenda.
Radars, like sound ranging and flash spotting, require hostile guns, etc. However, there are exceptions.
These accidental intercepts led to their dedicated use in this role, with special secondary instruments if necessary, and development of radarr designed for mortar locating. The radar can also be configured to scan less than degrees, providing focused sector coverage with more frequent update rates. Action on locating hostile artillery depends on policy and circumstances.
Until about this relied on conventional artillery survey, although gyroscopic orientation from the mids helped. It can be deployed in challenging locations previously unavailable to traditional counterfire radars, making it an ideal solution for force protection at Forward Operating Bases.
Once RAM is detected, the radar sends an early warning message indicating a round is incoming.
The distinguishing feature was that instead of just locating individual guns, etc. Please help improve this article by adding citations to reliable sources.
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 counterbattery artillery to hit it with ease.
The emergence of indirect fire in World War I saw the development of sound rangingflash spotting and air reconnaissance, both visual and photographic. However, self-propelled ones have been used since the s.
At pounds and 3. The radar can be assembled or disassembled quickly by two soldiers in 20 minutes. The first radars were developed for radae purposes just before World War II.
