N019M1 is the last variety of the N019 radar family.But there is few info on this radar,I've never heard that the radar has fitted on any aircraft.I want to know that had any N019M1 been made and used on any aircraft ????Could somebody tell me this?TIA!

i think it's is on russian 9.13 Mig-29s

N019m is on the later 9.13 Mig-29s
N019m1 is on Mig-29sm and smp

Here is an avionics doc on the MiG-29SMT. Have only browsed over it quickly, but seems to include some interesting stuff on the Zhuk and avionics in general

not SMT,this UPG

The document itself says its MiG-29 "Supershafaq". Yemen called its MiG-29s Shafaq, so at first sight its an upgrade for Yemen.

So correct me if I am misunderstanding, but it seems the range increase is mostly a velocity search type mode. The actual lock on range is pretty similar to N019.

It sorta seems that N019M and the Original N010 and then N019M1 and Zhuk-M(E) have similar overall detection and air to air performance. Zhuk radars are more flexible multimode radars while the N019 are perhaps lower risk?

Hi!
Hmmm..I was under the impression the N019 Rubin had a tracking range of at most 60km? Therefore, wouldn't Zhuk-M have about 20km over the N019 Rubin in a head on engagement? I would think that is a substantial increase in tactical capability, no?

In regard to a similar air to air performance as the N019 Rubin & N019M Topaz. I am not quite sure, but I would like to note that the Zhuk-M is a digital design with a planar array, I imagine the Zhuk has very minimal latency, lower side lobes, higher directivity along with high directional beam agility across its axes seamlessly compared to the hybrid, predominately analog mirrored design of the N019 & N019M.

I would bet that the Zhuk-M detects, tracks and prosecutes targets at a far greater speed & efficiency over the N019, N019M as well as the N019M1 to such a degree that any similarity in range performance would be negligible.
Also, as a general rule a radar's performance is largely limited its physical size. These are radars compatible with the Mig-29, It's should not be a surprise if there is some similarity in range performances.

while the N019 are perhaps lower risk?

Not sure I follow, are you perhaps questioning why the N019 is operational & in some cases chosen over the Zhuk?

Zhuk-M

Main Modes
Air-to-Air Modes

Rangefinder-search mode.

The radar detects air targets flying in free space and against the background of the underlying surface within the coverage zones in azimuth and elevation.

Frequency range – X. Number of letters (litera*) – 16

* "Litera" typically refers to PRF settings on Soviet radars.

Scanning mode characteristics.

The radar provides stabilization of the field of view relative to the horizon during the roll and pitch of the aircraft.

Number of bars 2-4
Maximum scanning angles of the antenna beam
● azimuth ±85º
● elevation +56º / -40º
● roll ±120º

Scanning modes
● small zone ±10º (2 bars)
● medium zone ±30º (4 bars), ±30º (2 bars)
● large zone ±60º (2 bars), ±60º (4 bars).
The minimum target speed for detection and tracking is 150 km/h in free space.

The radar provides the following values of detection range for an F-16 aircraft (σ = 5 sq m)

		Azimuth/range mode	Azimuth/speed mode
1	Front aspect, lookup	> 120 km	130 km
2	Front aspect, lookdown	> 110 km	130 km
3	Rear aspect, lookup	> 50 km
4	Rear aspect, lookdown	> 40 km

Here's the work in progress

Yo, Boss quick question in regard to the Soviet standard N019 antenna view parameters. I see that in National Aviation University Zhitomir Military Institute study you shared regarding N001 & N019 is a specification for view zone capability of the RLPK-29 listed below.

View Zone -azimuth ± 70 °-elevation -45°/ +60

My question is does the specification apply to the Soviet standard N019 view zone & its scan angle performance of platforms like the Product 9-12 for example?

I have seen these numbers before, but do not remember where. Does the view zone capability above represent the maximum scan angle or tracking zone in any capacity when it is listed?

Apologies if the answer is in the study, just started reading it now.

Cheers

The maximum azimuth is used during STT track. During search, the maximum azimuth is 65 degrees. If you lock someone at edge of gimbal limit in search in left or right direction, you could turn an oddities 5 degrees with STT before the lock is dropped

Hi, appreciate the reply.

However, what your provided is not correct & does not apply to the N019 Rubin or the N001 Mech. All information provided as well as the study in question is clear in the performance specified..

The maximum tracking zone performance for the N019 Rubin is long established at 65° elevation @ +56°/ -36. This is specified with no room for interpretation (by design) in the Soviet produced Mig-29 operators manual as well as sources & literature throughout the years. It is also attached in the very post you replied to.

Attached is additional clarification as well as the listed maximum view zone/area performance depending on target range etc. Never does the N019 Rubin exceed 65/70° azimuth & elevation +56°/ -36 under any conditions. Which is obvious when understanding the history & design of the radar.
In in regard to "gimbal" limitations in a single target track.
The N019 Rubin is equipped with a mechanical beam-scanning, offset front feed, polarization-twisting Cassegrain antenna that has no ability to "gimbal" like Western 3rd & 4th Generation parabolic & planar array antenna.
I don't think the N019 even gimbals at all but operates RF rotary joints.

The only moving part is a Main Twist reflector which is scanned. It must rely on a double-ridged feed and a wire grid paraboloid Sub reflector are fixed in place in place at the front of the nose. The twist reflector reflects the beam of the paraboloid while it rotates its plane of polarization by 90 degrees. The twisted beam passes through the wire grid paraboloid reflector. The N019 provides a uniform gain but retains terrible boresight/"Gimbal" performance.

If the listed performance by the National Aviation University Zhitomir Military Institute is correct (View Zone -azimuth ± 70 °-elevation -45°/ +60), this means the first Soviet production version of the N019 (Rubin) now has better elevation tracking performance than the slotted array Zhuk-ME @ azimuth ± 85 °-elevation -40°/ +56°. It also has the same positive elevation performance as the electronically scanned surveillance sector & total tracking sector performance of the Ibris-E for the Su-35.
