Description: Automatic target detection in SAR image is the first stage in the ATR (Automatic Target Recognition) system. It is very important to improve the computing efficiency of the whole system. A conventional automatic target detection method is CFAR (constant false alarm rate) which is based only on the amplitude, discards the phase and thereby sacrifices half information of the SAR imagery. Almost each CFAR brings a large number of false alarms. 2L-IHP (two-look internal Hermitian product) is a new method which exploits the phase and amplitude information. In this paper, both CFAR and 2L-IHP algotithms are compared with an emphasis on 2L-IHP. The 2L-IHP algorithm for target detection is discussed briefly first. In order to apply it widely, it is modified to circumvent the constraint of the data. For polarimetric SAR images, PWF (Polarimetric Whitening Filter) is used to generate an image for target detection. According to ADTS data set, these algorithms are analyzed and evaluated respectively. C-、L- and P- band AIRSAR data are also processed, and some tentative conclusions are derived: Considering the penetrating ability of the microwave, L-band got the best detection accuracy of the three bands; HH polarization performed better for target detection than VV and HV polarization; Moreover, because more information is contained in polarimetric SAR data, here, we conclude that polarimetric SAR data have advantages over single polarized SAR data when they are applied for target detection. But all these conclusions need further validation.

Description: AAC编码器的matlab实现，可以导出AAC编码中间过程的系数-Usage:
Take a wav file (44100, Mono) and name it as original_input.wav or change name in main_aacencoder.m.
1. Open the file main_aacencoder.m to encode original_input.wav in ADTS AAC format.
2. Run the file.
3. Check the output encoded_input.aac
4. Download FAADv2 decoder from http://www.rarewares.org/aac-decoders.php, or sourceforge.net/projects/
5. Place the windows binary faad.exe in this folder. To decode this encoded AAC file run decode.bat, it uses faad.exe to decode.
6. Open the file encoded_input.wav. Enjoy !!
7. Use Adobe Audition/GoldWave to open wav files, or use any media player for the same.

Necaise introduces the basic array structure and explores the fundamentals of implementing and using multi-dimensional arrays. The underlying mechanisms of many of Python s built-in data structures and "constructs are covered. A number of ADTs and applications are discussed as threads throughout the book to allow for multiple implementations as new data structures are introduced. Real-world applications of the various chapter topics are also presented. This gives programmers complete coverage of abstraction and the basic data structures and algorithms in the Python language.)
