Very nice thread. You look like an insider.

Pakistan air force is operating 5 types of combat radars as of now 3 of them are high level
radars and 2 of them are low/medium level radars , they are used to conduct ground control interceptions and also for surveillance of pakistani air space .
HIGH LEVEL RADARS:
TPS-77
L BAND, 3-D, tactical transportable long range air surveillance radar uses an active electronically scanned array (AESA), to generate a number of pencil beams.
The radar use a variety of interference rejection techniques. These include greater than 10 percent agile bandwidth, pulse-to-pulse frequency agility, low side-lobes, sidelobe blanking, MTI and constant false alarm rate processing, pseudo-random pulse repetition frequency, pseudo-random beam positioning, and a linear frequency-modulated waveform.Maximum search range is 250 NM
Specifications:
frequency: 1,215 to 1,400 MHz
pulse repetition frequency : pulsewidth (τ): 51.2 µs (short range) 409.6 µs (long range)
peak power: 19.9 kW
average power: 3.6 kW
instrumented range: 5 to 250 NM (10 to 470 km)
Beamwidth: hits per scan: 1 … 3
antenna rotation: 5, 6, 10, 12 rpm
MTBCF: > 2 000 h
Tps77 are the latest radars in Paf inventory and we can surely say that they are eyes and ears of paf , they have 33 transmitters and receivers in them . They are in service with 6 sqn's of paf
TPS-43G/J
Provides complete 3-D cover to 447 km on a fighter or fighter-bomber aircraft and measures heights over the full range by signal amplitude comparisons in six channels.Extensive clutter rejection and electronic counter-countermeasures features are incorporated in the design, including a digital coherent moving target indicator system, pulse-to-pulse frequency agility, Jamming Analysis and Transmission Selection , coded pulse anti-clutter system and side lobe blanking.
Specifications:
frequency: 2 900 - 3 100 MHz
pulse repetition time (PRT): 4 ms
pulse repetition frequency : 250 Hz
pulsewidth (τ): 6.5 µs
peak power: 2.8 MW
verage power: 6.7 kW
instrumented range: 450 km
Beamwidth: 1.1°
antenna rotation: 10 seconds (6 rpm.)
Tps43G inducted in paf around 1980/81 and Tps43j inducted in paf around 2003/2004 . These radars have saw live combat action in afghan war as well. They are in service with 5 sqn's of Paf/
YLC-2
a 3-D air surveillance and acquisition radar that operates in L BAND. The radar uses a phased array with an aperture of 7 m · 9 m that scans electronically in elevation while rotating in azimuth.The antenna array of the YLC-2 consists of many low-power radiating elements using solid-state power-amplifier modules mounted in 54 vertical rows. The main antenna is topped by an IFF/MSSR array. Maximum search range is 490km
Specifications:
frequency: 1,240 … 1,400 MHz
pulse repetition frequency : 275 Hz
peak power: 85 kW
average power: 5.5 kW
instrumented range: 330 km 500 km
range resolution: ≤ 300 m ≤ 200 m
accuracy: ≤ 100 m ; ≤ 0.3°
They were inducted in 2001/2 and probably the most quickest weapon induction in history of paf they are in service with 4 sqn's of paf
LOW-LEVEL RADARS
YLC-6
Highly mobile low altitude medium range surveillance radars that utilizes full solid-state transmitter, and an advanced MTD processor to enhance the radar survival capability and tactical performance.It's maximum search range is 150 KM
Specifications:
frequency: S BAND
pulse repetition frequency : 170 HZ
peak power: 175 kW
instrumented range: 180 km
range resolution: 150 m
Beamwidth: 1.5º
They are in service with 2 mission control centers in a mix with MPDR's
MPDR-45/60/90
2D short-range low-level surveillance radar operating in L Band. radar antenna is extensible with a hydraulic mast at a height of up to 13 m. The truck MAN 630 L2AE (5 metric tons) served as a carrier vehicle. It is a solid state radar (without the transmitters power tubes and the displays CRT) and transmitted frequency is crystal-stabilized.They are part of paf's PAD 77 plan .They are in service with all 7 MCC's of PAF and in 2 MCC's they work alongside with YLC-6.
Specifications:
frequency: L BAND
pulse repetition frequency : 155 HZ
instrumented range: 45,60,90 km
MTBCF: 300 hrs
