Sastay mein bak gaye, nai ?No the deal is for used b52..not Vs
Vs will only come of pakistan settle issues with india
The good thing is that Block-52+ have Pulse Doppler (PD) radars which has inherent Electronic Protection (EP) features like:
1.It expects its return in a narrow frequency range, so it can discriminate against noncoherent jamming.
2. t can see spurious outputs from jammers.
3. It can see frequency spreading from chaff.
4. It can see separating targets.
5. It can correlate range rate and Doppler shift.
Jamming a PD radar is tricky so if a jammer is to deceive a PD radar it must generate a coherent jamming signal. When a jammer has a digital radio frequency memory (DRFM), it will be able to measure the frequency (and other parameters of PD radar) of the first pulse it sees and make accurate copies of all subsequent pulses during the time the radar beam is covering the target on which the jammer is located. A PD radar can have multiple operating frequencies, thus frequency diversity. A more challenging use of frequency diversity is assignment of one frequency per sweep of the radar antenna. This gives the radar the advantage of a single frequency during its coherent processing interval. Because the jammer cannot anticipate the frequency of future pulses, it is impossible to optimally jam the radar. Also PD radar can be expected to avoid frequencies at which jamming is detected, so jamming a few of the frequencies is unlikely to improve the jamming performance.
Another thing, since a PD radar can detect jamming, it will allow any missile system that has a home-on-jam capability to select the home-on-jam operating mode. If the radar detects jamming, it can then go into a home-on-jam mode, causing the missile to steer itself toward the jammer. This feature makes it very dangerous to use self protection jamming for terminal protection. Because this mode can also be used against a stand-off jammer, it can threaten this high-value/low-inventory asset if the BVR missile has sufficient range to reach the stand-off jamming location.
The PD radar has three types:
Low PRF is very useful for target acquisition
Medium PRF was developed to enhance tail chase engagements.
High PRF is ideal for use in a high speed head-on engagement with a target
Now, is F-16 PD radar composed of all three types ?
