The ZA-35 Spaag based on the Rooikat has a system of optronics/laser rangefinder developed by Eloptro, but what radar is used on that vehicle?
It was the L-band EDR 110 - in fact this formed the basis for most of the other and larger radar development that ESD-South developed (Later becoming Reutech Radar Systems) - obviously communality played a big role as well - but some of the reasons are evident in the explanation of the L-band choice for EDR 110 in the article below, as the same reasons for using the EDR 110 as the base to work on.
The article also covers the EOT tracker, Radar/Optronic tracker and the commander's site - although not all applicable to this this, they are included for completeness (I think this article will answer a lot of ZA-35 SPAAG questions for you
No brochure on the EDR 110 that I know of, I think it was never meant to be sold separate the the ZA-35 SPAAG anyway. What has been stated is that the EDR 120/140 mobile radar is in fact the towed derivative of the EDR 110, just with slightly increased range (17km's instead of 12km's). I suspect that the picture in the brochure below actually shows the 140 version, but that's just my guess.
