The receiver uses a 50-channel, range-gated filter moving target indicator (MTI) processing that can be switched off to locate fixed targets. Each gate covers 109 yd (100 m) of distance from the radar and it is a summation of all 50 channels that provide the video display. Range measurement is manu al, using a magneto-restrictive delay line.
The PPS -5 consists of three packages, all of which can be man-carried.
In 2001, Canada signed a contract for US$13 million with Engineered Support Systems of St. Louis for the production of an unknown number of MSTAR systems. The MSTARs were integrated into the LAV III artillery reconnaissance vehicle. Deliveries began in 2002 and continued throughout 2003.

The simple parabolic ellipse is made of Kevlar to absorb battle damage and still function. The antenna does not rotate and is initially set by the crew member.
The solid-state system has five multi-layer signal-processing boards and can handle up to 99 target tracks at a time, displaying 10 of them at once.
The display is separated from the radar by up to 66 ft (20 m) of cable. The display is electroluminescent. When in the plan-position indicator (PPI) mode, it can be scaled to standard maps. On the left, the numeric keyboard allows entry of initial parameters. To the right, a compass-rose style keyp ad moves the cursor. Surveillance or acquisition modes can be selected. If the B-scope acquisition mode is selected, the radar can "zoom" on a 0.42-sq mi (1.1-sq km) "area of interest." Thorn EMI claims that the radar has low-probability-of-intercept (LPI) characteristics.
The current MSTAR man-portable radar, by Racal Radar Defence Systems, is virtually the same as the AN/PPS -5, except that the J band for the British MSTAR operates at 10Ghz-20GHz compared with the U.S. version with a range from 16-16.5GHz. A new variation of this radar is the MSTAR 1-10, which allow s selection of the power output from 1W to 10W, making the system harder to detect.
Initial operational capability of this model was in 1990. First unveiled in 1987. In production for the British army for use in the Warrior mechanized artillery observation vehicle (MAOV).
The standard control display assembly/unit (CDA or CDU) has been replaced with an optional man/machine interface (MMI) that uses PC Windows-based software, allowing the soldier to interface with digital map overlays via CD-ROM.
MSTAR also features a built-in maintenance package that allows the radar operator to isolate and repair most problems in less than 30 minutes.
MSTAR can provide valuable information to the artillery in support of counter-fire, by providing correction of fall-of-shot of friendly fire relative to the intended target.
The AN/PPS -5C (Ku band) has met military standards for: blowing rain, washability, sand and dust, ice/freezing rain, vibration, shock, audibility, humidity and EMI.
MSTAR was deployed in Saudi Arabia in 1990-1991 with forward artillery observers of the Royal Artillery as part of the British contribution to operations Desert Shield and Desert Storm.
The MSTAR was also used during the conflicts in Bosnia, Afghanistan and Iraq.
