The SLC-2 Radar is a counter-battery radar designed to accurately locate hostile artillery, rocket and ground-to-ground missile launchers immediately after enemy firing, and to support friendly artillery by providing guidance of counter-fire. SLC-2 radar can also be applied in adjusting firing of friendly weapons or rockets. With slight modification to software parameters, SLC-2 radar can also be used to detect and track low flying targets such as light aircraft, helicopters and RPVs. SLC-2 systems have sometimes been mounted on a Dongfang EQ2102 3.5 ton truck. Four AN/TPQ-37 Firefinder radar have been sold to China and this had become the foundation of SLC-2 radar development. Aside from political reasons, the US$ 10 million plus unit price tag of TPQ-37 (including after sale logistic support) was simply too costly for Chinese. Decision was made to develop a domestic equivalent after mastering the technologies of TPQ-37. After the initial test of TPQ-37 in Tangshan (ฬภษฝ) Range near Nanjing in 1988, and in Xuanhua District in October of the same year, several shortcomings of TPQ-37 were discovered and further intensive tests were conducted and completed in 1994. The requirement of the Chinese domestic equivalent was subsequently modified to address these issues revealed in trials. Due to the limitation of the Chinese industrial capability at the time, decision was made to develop the Chinese domestic equivalent in several steps. The first step was to develop a smaller one, which would result in the Chinese equivalent of AN/TPQ-36 Firefinder radar, and based on the experience gained from this program, a more capable larger version in the same class of AN/TPQ-37 Firefinder radar would be developed, which eventually resulted in SLC-2 series.
