MADRID, July 29 (Reuters) - Spanish IT firm Indra (IDR.MC) narrowly beat forecasts with a 7 percent rise in first-half net profit to 108 million euros ($152.8 million) on Wednesday and maintained guidance in spite of a market slowdown, especially in Spain.

Analysts polled by Reuters had expected net profit of 104 million at Indra, whose technology controls Spain's high-speed rail lines and whose radars protect its coastline.

"The months that have passed so far this year have confirmed the lethargic and low growth of some markets in which the company operates, especially the domestic market," a company statement said.

"In the second half of the year, international markets will continue to be the group's main driver of growth. The domestic market is expected to (be) flat in the second half of the year."

Earnings before interest and tax (EBIT) rose 7 percent to 152 million euros, versus a 148.8 million euro consensus in the poll of 14 analysts.

New orders were up 4 percent to 1.54 billion euros while its order book increased by 6 percent to 2.6 billion.

Indra reiterated its full-year 2009 objectives including maintaining the EBIT margin at 11.4 percent and revenue growth of between 5 and 7 percent. ($1=.7069 Euro) (Reporting by Ben Harding; editing by Simon Jessop)
