I am currently doing a project named ultrasonic radar.It uses an ultrasonic module and a servomotor.tThe distance is obtained from ultrasonic module and angle from servomotor. It is displayed on the serial monitor. Can I use APC 220 module in the tx pin of arduino and obtain the values in the serial monitor wirelessly in PC?can I make any changes in the existing program?

An APC220 is effectively transparent, and acts just like a hard-wired serial connection. After configuring the modules, you just need to ensure that the baud rates match your code and the serial monitor. I usually set my APC220s up for a serial speed of 9600 baud with parity disabled, and an RF rate of 19200 baud.
(For longer-range comms, a slower baud rate of 2400 or even 1200 is better.)
Also ensure that the frequency of the two APC220 modules matches, of course.
The configuration software is available here, if you don't already have a copy:- RF-Magic Configure software
The datasheet is here:- APC220 Datasheet
Can I use tx pin of arduino to transmit data?can I use processing window at recievwr on PC?

Whether I have to include any additional library or modify the program?

No libraries. I thought I made it clear. Just configure the modules and set baud rates appropriately.
Be aware though that it cannot connect directly to an existing serial port on the PC. The APC220 has a TTL interface. You need to use a serial to USB converter for connection to a PC USB port, or a MAX232 driver to connect to a serial port directly.
This page, (which I think you've already seen, if I remember correctly), explains everything:- APC220_Radio_Data_Module(SKU_TEL0005)-DFRobot
Please read all of the documentation.
Remember that Tx and Rx are applicable to their own module only. This means you have to cross over between modules. Arduino Tx goes to APC Rx pin when Txing.
PC Rx is connected to APC Tx.

This is self-expanatory, I thought:-

Edit: In your other thread, I had already provided the link that I re-posted in reply#5 of this thread. If you'd read that page thoroughly, you wouldn't need to ask these questions - all is clearly explained with pics and a code example.
Edit2: Also on that page is a link to a further page here http://www.dfrobot.com/forum/viewtopic.php?f=5&t=1497 with downloadable TX and RX examples that clearly show that no libraries are needed.
As I said earlier - read the documentation. All I can do is regurgitate what's already covered on those pages.
