====Ground Tactical Radar MASINT====
A variety of ground-to-ground radars serve in counterbattery and surveillance roles, and also have some capability to detect helicopters. The LCMR, AN/TPQ-36, and AN/TPQ-37 radars are ideally used in a layered detection system, for short, medium, and long range detection. LCMR is omnidirectional, but the other two are directional and need cueing from omnidirectional sensors such as the combined electro-optical and acoustic [[Electro-optical MASINT#Rocket Launch Spotter | Rocket Launch Spotter]] or a pure acoustic system such as [[Geophysical MASINT#HALO| HALO]] or [[Geophysical MASINT#UTAMS| UTAMS]]
=====Lightweight Countermortar Radar (LCMR)=====
Line 72:
As its name suggests, it was optimized to detect mortar round signatures, and is not reliable for detecting light rockets fired in an indirect trajectory. It detects threats in the 360 degrees surrounding the antenna, out to a range of 7,000 meters.
=====AN/TPQ-36
Physically heavier than the LCMR, the Q-36 can detect cannon, rockets, and mortars within its range:▼
These 1980-vintage systems are not man-portable, and are directional, but they do have longer range than the LCMR.
▲Physically heavier than the LCMR, the
:*Artillery: 14,500 meters
:*Mortars: 18,000 meters
Line 81 ⟶ 84:
It has a moving rather than omnidirectional antenna. Current improvements are intended to replace its old control computer with a laptop, enhance performance in high clutter environments, and increase the probability of detecting certain rockets.
First intended to provide a third tier against long-range threats, the Q-37 basic software filters out all other radar tracks with signatures of lesser-ranged threats. New software, required by the mortar threat in the Balkans, allows it to duplicate the Q-36 mortar detection range of 18 kilometers, while still detecting longer-range threats. Proper crew training should compensate for the reduced clutter rejection caused by accepting mortar signatures.

Standard TPQ-36/37 radars are semi-manual in their plotting. An Israeli enhancement makes the plotting fully digital
