What if the jammer that can interfere with monitoring can't find the anchor point?

Jammer that can jam monitoring can't find the positioning point: my own jamming direction finder can accurately measure the emission direction of jamming source, and combined with topographic map, the approximate position can be determined by selecting two points for cross positioning. If combined with GPS latitude and longitude measurement, it can be accurate to within 10 meter.

Exposure of digital movies: lens-spectroscope -CCD-A/D analog-to-digital conversion-black spot correction-gain adjustment-white balance-stray light correction-detail adjustment-color giant array-inflection point adjustment-GMA adjustment-white cutting and black cutting.

The exposure of film movies is controlled by the exposure meter. Some digital photographers also use exposure meters. Generally, the sensitivity of digital cameras is similar, and for SONYF900, it is at 3200K color temperature.

Adjacent channel interference:

VHF and UHF radio stations widely used in mobile communication systems have a channel spacing of 25KHz. As we all know, the frequency spectrum of FM signal is very wide. Some harmonic components fall into the passband of adjacent channel receiver, which will cause adjacent channel interference. This kind of interference is mainly caused by the serious unqualified technical indicators of the transmitter.

Generally, the frequency stability of the transmitter is required to be 5×10-6 when multi-base stations work; The maximum allowable frequency offset of modulation is 5 KHz. The paging system in China is set to 4.5 KHz；; The adjacent channel interference caused by the adjacent channel radiation power to the adjacent channel receiver should be more than 70dB lower than the carrier power.
