SAR成像处理基本知识2——图像尺寸与回波尺寸的关系阅读本文前，请先了解上一篇文章（SAR成像处理基本知识1——常用专用名词解释） 1. SAR图像尺寸预估方法以C波段2m@20km的SAR图像为例，假设天线中心下视角为35° ，说明图像尺寸的估计方法。 1.1 距离向尺寸估计地距分辨率为2m时，距离向分辨率约为1.15m，则要求信号带宽不小于130MHz，假设信号带宽为150MHz，采样率为180MHz，那么距离向分辨单元为0.833m。地距幅宽为20km时，距离向幅宽约为20*sind(3... 阅读详情

Compiler Error C2065
'identifier' : undeclared identifier

The specified identifier was not declared.

A variable’s type must be specified in a declaration before it can be used. The parameters that a function uses must be specified in a declaration, or prototype, before the function can be used.

Tips

Make sure any include file containing the required declaration is not omitted.

Make sure you are including any necessary header files if you have defined VC_EXTRALEAN, WIN32_LEAN_AND_MEAN, or WIN32_EXTRA_LEAN. Defining these symbols excludes some functionality (certain header files are excluded) from windows.h and afxv_w32.h (for MFC applications) to speed compiles. Search windows.h and afxv_w32.h for these symbols for the most up-to-date description of what is excluded.

Make sure the identifier name is spelled correctly.

Make sure the identifier is using the correct upper- and lowercase letters.

Make sure all string constants have closing quotes.

This error can be caused by having a newline character in a string constant without a continuation character. For example:
#include <stdio.h>
main() {
printf("\n %s
%s // error: 's' : undeclared identifier
%s",
"this", "is", "it");
}

Special considerations must be taken when splitting a constant string over several lines. The most common method is to change the format string. Strings separated only by whitespace (spaces, tabs, newlines) are concatenated. For example:
#include <stdio.h>
main() {
printf("\n %s"
" %s"
" %s",
"this", "is", "it");
}

An older, less-preferred method is to use line continuation by typing a backslash at the end of a line. For example:
printf("\n %s %s %s",
"this", "is", "it");

This method is not often used because the spaces at the beginning of each continued line become part of the string.

Make sure you're using proper namespace scope. For example, in order to properly resolve ANSI C++ Standard Library functions and operators, you must state that you're using the std namespace with the using directive.
For example, unless the using directive is uncommented, the following sample will fail to compile because the cout stream is defined in the std namespace:

#include <iostream>
// using namespace std;
void main()
{
cout << "Hello" << endl;
}

他们的头文件没有包含进去

#include "Shlwapi.h"

在你的maindlg.cpp前面添加这两行看看。
