Chirp how does it work

The pulse compression process, used in both radar and sonar systems, converts a long duration frequency-coded pulse into a narrow pulse of highly increased amplitude. A narrow pulse with high peak power can be correlated from a long duration pulse with low peak power, increasing the range resolution and improving the signal to noise ratio, giving the device greater ability to pull targets from the background noise.

CHIRP improves bottom tracking at higher speeds and deeper depths. It helps resolve individual targets—no blobs, but instead crisp separation of adjacent objects.

The result is a spectacular improvement in the image you see. Then, when you find something that looks good, get a closer look on the tighter-focused high CHIRP setting. When this technology first showed up on the market, CHIRP could only be found in expensive sonar modules costing a couple thousand dollars.

They were made for the pros and for offshore fishermen looking for the latest technology, regardless of price. If you are using a clone-mode radio, you may wish to save a.

Live mode radio users will have their changes immediately take effect in the radio and do not need to proceed to Step 3.

Once you have made all the edits you need to make, you should upload your image back to the radio. With your image open, go to the Radio menu and choose Upload To Radio. The Vendor and Model are already known, so all you need to do is choose a serial port. Note for Yaesu radios: Like the download procedure, the upload procedure must follow a particular sequence.

Make sure that your radio is already in clone mode and it is already waiting for an incoming clone transmission. If you wish to save memories from an existing radio out to a generic file that can be imported into other radios or edited by hand, use the Export function in the menu. If you have an image from another radio even another type , you can import that into an image or live mode radio using the Import function in the menu. Sign in Register. Search :.

This is a test. The ability to use CHIRP depends greatly on the brand and model of electronics you use, so make sure to check with your manufacturer for specifics. Marine Electronics Tips. Fishing Videos. Giveaways Giveaways Giveaway Winners.
