Matla-ul-fajr can use 100 different frequencies in the VHF band to operate in jammed environments."Panjereh Magazine" weekly number 38

In the same year, a project to enhance the capabilities of radar was started by SAIRAN and Isfahan University of Technology. Production of this model called Matla-ul-fajr 2 was started in 2012.{{cite web|url=http://www.mashreghnews.ir/fa/news/86059/%D8%AA%D9%88%D9%84%DB%8C%D8%AF-%D8%A7%D9%86%D8%A8%D9%88%D9%87-%D8%B1%D8%A7%D8%AF%D8%A7%D8%B1-%D9%85%D8%B7%D9%84%D8%B9-%D8%A7%D9%84%D9%81%D8%AC%D8%B1-%D8%AF%D8%B1-%D8%A7%DB%8C%D8%B1%D8%A7%D9%86 |title=تولید انبوه رادار مطلع الفجر در ایران – مشرق نیوز |publisher=mashreghnews.ir |date= 20 December 2011|accessdate=2012-10-28}}

State-owned Mashregh News reported that Matla-ul-fajr 2 is a solid state 3D radar operating in VHF band. Due to the nature of its frequency, it can detect low-Radar cross-section targets such as stealth aircraft and cruise missiles with low accuracy at shorter ranges. The range of the radar is {{convert|480|km|mi}} and it uses two separate channels for detection and is installed on the back of heavy trucks to enhance mobility. This radar won the first place in Kwarazmi International Festival.
