Here is .pdf I came across basically by accident from the NJ Transportation Planning Authority.
http://www.njtpa.org/About/Business/...dix_vol_VI.pdf
It lists the new projects for the NJTPA for 2007-2008. On page 130-131 of the document they talk about thier plans to upgrade the radar units for the State Troopers to Ka-band and to make sure that it will be admissable in court.
Below I have pasted the relevant text from the article:
STATE PLANNING AND RESEARCH PROGRAM, 2007 - 2008
ACTIVITY :
Analysis of KA-Band vs X-Band Radar - 4500007/7727
MANAGER:
Edward S. Kondrath
UNIT:
Bureau of Research
PURPOSE:
This project focuses on an integral component of the New Jersey State Police commitment to highway safety in enforcing posted speed limits. Effective enforcement of speeding statutes requires the methods employed to measure speed are accurate and state of the art. This requirement is necessary in
order to successfully prosecute by using both moving and stationary radar. The Division currently utilizes
MPH Industries K55 radar unit. This is an X-band radar that has been tried and tested in New Jersey
Courts. With the advent of new technology being introduced to the interior of the Troop vehicles, the lack
of space has become an issue that can no longer be ignored. K55 is a good tool, however it is very large,
and has to be mounted on the dash of the vehicle. This presents the possibility that it can become dislodged
in the event of a motor vehicle crash, and cause subsequent injury to the front seat occupants of the vehicle.
In 1955, the case of State of New Jersey vs. Dantonio, 115 A2d 35, 49 ALR2 d 460, the courts took
judicial notice of police traffic radar operating on the Doppler Principle.
The most recent case dealing with moving radar, specifically K55, (the unit predominantly used by the
Division), is State vs. Wojtkowiak 174 N.J. Super 460 (1980). The courts have taken judicial notice as to
the scientific reliability of the K55 radar. This is predicated on the competent operation of the radar, after
the operator has been trained in its use. (S.O.P. F-20)
The New Jersey State Police have solely used K55 as a speed detection device in the moving mode. Other
stationary means of speed detection have been used, e.g., VASCAR and stop watch speed timing. Both
methods did not employ radar.
New and innovative programs like the introduction of the Ka radar speed detection device enables the
Division of State Police to enhance our speed enforcement program to better serve the motorists who travel
New Jersey’s highways
OBJECTIVES:
The objectives of this study are to:
1.
Examine the state of the art in model development for KA-Band Radar .
2.
Prove or disprove that the new technology (KA-Band Radar) is at the least as reliable as the current (X-Band Radar). 3.
Identify data deficiencies and statistical validity of alternative approaches.
4.
Develop requirements and standards for KA band radar for all the requirements that are imposed by the Court system to be accepted as an instrument TASKS/ACTIONS:
Report progress on quarterly basis
PRODUCTS:
Task 1
: Literature search. This is a more comprehensive and focused search. Task 2 Collection of Data Task 3: Analyze Data

Task 4.
Prepare in interim report that discusses alternative approaches to model development and
incorporation. Discuss data needs and availability for model calibration and use.
Task 5.
This task shall include documentation of quality control procedures that will be used by the research team for coding, calibrating and applying models. A technical memorandum will be prepared and presented to the RSIP.
Task 6. (If appropriate)
The purpose of this task is to implement and calibrate one or more of the proposed alternative systems. The research team will code approved alternative models, calibrate the parameters and determine statistical validity. A technical memorandum will be prepared and presented to the RSIP.
Task 7.
The purpose of this task is to ensure that the research project has been properly documented. A draft final report, based on the technical memoranda prepared in prior tasks, shall be prepared for RSIP review and comment. The RSIP shall provide comments to the research team, which will prepare a
response to comments document for review and approval of the RSIP. A final report shall be prepared
incorporating all changes needed to resolve the comments.
EXTRAORDINARY ACCOUNTS:
