A--The US Army CERDEC Intelligence and Information Warfare Directorate (I2WD) has a requirement for two enhanced Lightweight Counter Mortar Radar (LCMR) systems.

The LCMR provides continuous 360 degree surveillance using an electronically scanned antenna. When a mortar is detected, the LCMR sends a warning message indicating a round is inbound. After sufficient data is collected to enable an accurate weapon location the weapon location is transmitted. Additional information regarding the performance achieved in the current version of LCMR is specified in the information under the title Performance of the Lightweight Counter Mortar Radar(LCMR)Pre-Production Mo del. Sources would be expected to improve upon the existing capabilities in one or more of the following areas: Reduced weight or size o Configuration for jump pack desired - Improved False Location Rate o Desirable for the system to maintain its false location rate when operating in an active airfield environment with aircraft taking off and landing. - Improved Impact Prediction (Specified Accuracy) - Improved Target Location Error (60m desired) - Increased Range: o 8km vs 81mm mortar o 10km vs 120mm mortar - Reduced minimum range (500m desired) - Inclusion of automatic digital communications, especially call-for-fire and early warning messages. - Vehicle Mount Capability o Include Hardening for transport (shock/vibe) while assembled. - Automatic self-survey; position and northing - Multiple selectable AZ sectors - Increased number of simultaneous tracks - Improved Maintainability o Antenna Calibration in-the-field - Full MIL-Environmental compliance - Reduced assembly time o Minimize parts counts Those sources who have established expertise in the development and production of radars for the location of indirect fire weapons capability are encouraged to submit a white paper (10 pages or less) on their capability and experience.

PERFORMANCE OF THE LIGHTWEIGHT COUNTER MORTAR RADAR (LCMR) PRE-PRODUCTION MODEL: 3.0 REQUIREMENTS 3.1 Item Definition The LCMR provides the ability to detect and locate mortar firing positions automatically by detecting and tracking the mortar shell and then backtracking to the weapon position. The LCMR provides continuous surveillance using an electronically scanned ante nna. The LCMR has been designed to be compatible with airborne operations and can be deployed in a door bundle. The system can be assembled and disassembled quickly by two soldiers. When a mortar is detected, the LCMR sends a warning message indic ating a round is incoming. After sufficient data are collected to enable an accurate weapon location, the weapons location is transmitted. 3.1.1 Functionality The system has been tested for its ability to perform automatic detection, classification, and location of incoming mortars. The system has demonstrated performance of these fu nctions without any operator interaction, except for system initialization in formation. LCMR has demonstrated the ability to: a. Perform radar functions (detect, track, etc.) b. Discriminate between mortars and other tracks c. Accurately locate weapon firing positions d. Communicate information to operator e. Operate on battery power f. Meet Emplacement / Displacement times g. Meet Maint ainability requirements (Fault detection, isolation, and repair). 3.1.2 System Configuration The radar system configuration is defined as consisting of the following: a. Radar Antenna, Receiver Signal Processor Group b. Battery / Power Supply Assemblies c. Remote Control and Display unit (Pocket PC/PDA) d. Mission Planning Computer e. Mechanical Assembly (tripod, cover) 3.2 Characteristics 3.2.1 Target Type Primary targets for detection, location and classification are mortars. Secondary targets for track and identification are light artillery and rockets. For the purpose of defining system performance, a target will be considered to be valid if it meets the following criteria: Minimum muzzle velocity: 65 m/sec Maximum muzzle velocity: 320 m/sec =?646?Q?The target must achieve a minimum height above the local terrain mask of 200 mils as observed from the radar and remain in the radar surveillance coverage for a minimum of 2 seconds. 3.2.2 Location Range LCMR is capable of locating 81 mm mortars to the specified accuracy from 1 km to 5km and 120 mm mortars to the specified accuracy from 1 km to 6 km. 3.2.3 Azimuth Coverage The radar azimuth coverage is 360 degrees. The system is capable, via operates PDA, of setting the azimuth scan between and 360? 3.2.4 Probability of Location Probability of location is defined as the probability of detecting and computing the point of origin of in-flight projectiles. For an individual weapon firing a single round in a benign non-jamming environment, the probability of location has been demonstrated to exceed 85% averaged over all weapon firing azimuths and weapon ranges within the required location range of the radar. 3.2.5 Location Accuracy LCMR has demonstrated Target Location Errors (TLE) of better than 100 m (50% CEP) for the maximum specified location range on each target type, averaged over all weapon firing azimuths and weapon ranges within the required location range of the radar. 3.2.6 Target Track Capacity The radar is capable of maintaining track on 20 simultaneous in-flight projectiles originating from separate sites randomly distributed in the coverage area of the radar. The probability of location under these conditions is greater than 85%. When addit ional projectiles are being tracked simultaneously, the probability of locating a new weapon firing may degrade. 3.2.7 In-bound/Out-bound Mode of Operation The radar performs friendly (out-bound) projectile impact prediction and hostile (in-bound) weapon location and projectile impact point prediction. The radar is capable of simultaneous in-bound/out-bound operation. 3.2.8 Hostile Projectile Impact Prediction The projectile impact point is predicted. (No accuracy requirement) 3.2.9 False Location Rate The radar has demonstrated a false location rate no more than one (1) per six (6) hours over a 24 hour day/night cycle. A false location is defined as an indication by the radar that an in-flight projectile has been detected and a firing point located when , in fact, no projectile has been fired. This performance was achieved in a benign (no local aircraft activity within 5 km) environment. Distant (less than 5km) aircraft have displayed no tendency to cause false locations. 3.2.10 Operation 3.2.10.1 Height Correction The radar system accepts Level 1 DTED data and automatically performs height correction. 3.2.10.2 Target Classification The radar system , as evidenced from demon strated PL, is able to discriminate mortars from aircraft targets. 3.2.10.3 Zonal Control.
