This Czechoslovak passive search engine was developed mainly on the basis of the patents of doc. ing. Vlastimil Pech CSc., who was the first to bring the technique of target detection using the time-domain hyperbolic method, a system nowadays called TDOA (time difference of arrival), to such perfection that it was possible to track the target accurately and display it in real time.

Its development began based on the need to cope with the deployment of US TM-61 Matador (also designated MGM-1 Matador) missiles in Germany. Initially, the possibility of jamming them was investigated. After V. Pech pointed out the unreality of this jammer, the development of a searchlight capable of determining the positions of the control radars was started. Paradoxically, the developed searcher was eventually more valid in other areas than in this one.

The research work began in March 1961 at the Radiological Warfare Research Center in the Department of Military Radiological Warfare at the Antonin Zapotocky Military Academy. Test operation of the prototype continued in the summer of 1961. In 1962-63, company trials of the first manufactured unit were conducted.

While testing the equipment, the crew somewhat unplanned managed to find the location of the top secret base of the first anti-aircraft missiles on the territory of the then Czechoslovakia. But it also managed to locate several Western air defense radars, including the missile's Matador control radar, which encouraged its further development.

In November 1964, tests of a pair of kits, with changes already made based on previous test operations, were conducted in the Ore Mountains. At the end of the year, they were moved to the border with Germany in the Bohemian Forest at the Havran and Velký Zvon stations. They were put into user operation there on 2 January 1965.

The system allowed the manual tracking of 6 targets (this value is, due to the system of evaluating information from the searchlight, rather theoretical). It operated in the S,L and X bands.

The set consisted of a central and two side stations (targeting and evaluation stations. The evaluation part was still electron tube, the first transistors started to be used only in the next type KRTP-81 Ramona). The stations were connected by MT-11 radio relay stations (originally used by CS TV). When a target was detected by the central station, the frequency of the target was reported to the side stations and the position of the target was manually determined in the operating station according to the detected values. The stations were operated on Praga V3S vehicles. 1 vehicle for each side station and 2 vehicles for the middle station (middle station + evaluation station), 4 vehicles in total.

It was used until 1979 in the number of the two rigs mentioned above, and was succeeded by the KRTP-81 Ramona system, which was fully automated. This was followed by the KRTP-86 Tamara and Vera systems.

In the US, attempts were made to develop similar systems based on information in a book passed on by a member of the PRP-1 system operator who defected in 1968. Supposedly, the AGTELIS (Automated Ground Transportable Emitter Location Identification System) and PLSS (Precision Location Strike System) projects were developed based on this information. Both were eventually cancelled.

This should be the evaluation unit. I can't trace the origin of the photo anymore.
